i have custom dll built with Delphi that used to work on IIS 5/6/7. After i migrated to apache, DLL started to crash after an hour or two and i have to restart the server. The error was something about bad header. Since the developer says DLL is handling reponses OK and i can't get anything with debug logging on apache side can i run DLL as CFG/FastCGI (not that versed with apache so maybe this question does not make sense)?
View 4 RepliesI've been having problems for the past two weeks. Apache and MySQL kept crashing. I tweaked MySQL, and MySQL stopped crashing. But Apache still crashes, sometimes twice a day, sometimes once every few days. It's driving me crazy. It started around the same time I acquired a new customer, so it's possible the customer has some sort of script or something that is causing problems, but I'm not quite sure how to determine whether the problem is the server itself, or if it's the customer.
So here am I, asking you experts for whatever assistance you feel willing to render. Even if you only merely read it, I thank you for at the very least taking the time to read it. Thanks in advance for any and all assistance given. That being said, here's the information the "How To: Request help from the experts" sticky recommended giving. I also took the liberty of including httpd.conf and my.cnf. I apologize if that resulted in being too much information, and humbly ask a moderator to "white out", or so to speak, (or at least point out) the information that shouldn't be shown.

httpd 2.4.4 x64 with php 5.5 x64 and mysql 5.6 x64, it worked just fine the first few days, but after a week or so, I'm starting to get this error:
[mpm_winnt:notice] [pid 1928:tid 552] AH00428: Parent: child process 8092 exited with status 255 -- Restarting.
What can cause that and how can I fix it?
I've got a complicated problem and I can't figure out what I need to edit to fix this.
I've been messing with the httpd.conf and php.ini files trying to optimize them as best I can. I've managed to get the load to stay pretty low all day, and everything seemed to be working fine. But then apache crashes.
(See screenshot for details)
httpd starts out with 70-150 VIRT memory, and it constantly goes up all day, and I've yet to see it go down. And, eventually it just crashes Apache! In the screenshot it's 502m, but I've seen that get as high as 800! And sometimes I even see a number like this "80376" no "m" or anything, just "80376"; I've no idea what that's about.
So what do I need to edit or tweak to fix this?
I'm on a cPanel linux server, Apache 2.2.8 and PHP 5.2.6.
It's been happening on both my old and new server, was really hoping this would be fixed.
Basically, the httpd/apache service crashes or goes down making domain names and sites unable to load; although cPanel/WHM still accessible. This would go on for about 5 minutes OR until I restart httpd in root.
sites simply do not load or just timeout after a period of time.
This has become extremely annoying for both me and my clients because it makes it seem like we have downtime.
Apache keeps increasing processes and when it reaches 256 value, it crashes. These are the values from our conf file. This doenst happen everyday, it occurs once or twice a week and at random timing.

I am trying to encrypt my session using the following directive
Session On
SessionCookieName session path=/
SessionCryptoPassPhrase sec
We are using form based authentication.
use of SessionCryptoPassPhrase crashes the server. If I dont use that directive it does not encrypt and works fine.
I see this error in application event log

Right now I am using the built-in cpanel backup feature to backup all the accounts on my server to an offsite FTP backup account I have on a weekly basis. The problem I am having is that everytime the backup runs, the load (thats what I'm guessing is the cause) is crashing apache/bind, causing sites to be unreachable until I can restart the services. What options do I have to resolve this issue? Currently I already have spri installed, and it does help out a bit, but its still not enough.

Is godaddy's windows hosting any good?
I update the corporate website for my company. Our server is IIS and when I need a 301, I have to send a request to IT to do it, as our pages are static .html and .shtml (SSI) and using javascript redirects is not ideal for SEO.
A redesign we're going to be deploying, will include the shuffling of several pages/directories and redirecting of quite a few URL's. This fact alone seems to provide a good argument convincing IT that this is a good idea. From what I've read here and elsewhere, heliontech's solution seems to be the way to go.
Since this is 3rd party, I'm looking to have further leverage to explain my case on behalf of using this. Are there benchmarks and data that support the reliability of this method versus the straight MS stuff?
Also, I'm not real tech savvy on the server end, but I was told that our corporate site and application sites may reside on the same box and that applying the ISAPI rewrite would affect those as well. This would obviously make it a "no sell" with my IT colleagues.
Would sites residing on the same server be globally affected by the ISAPI? If so, is there a way to circumvent this and just set the ISAPI for the one site?
So I have been reduced, I am a firm *nix Apache user, to using IIS along with ISAPI for redirection at work. Now I can setup the redirection(s) just fine using the GUI, but I am a *nix man and doing this through the GUI is SLOW! That is when it has to be done on 3 servers at a time plus I can only access those servers through a Citrix environment.
And I need to be adding redirects many times a week. Is there any way to setup ISAPI redirects from a command line? Google has offered me nothing.
have to say the EE forums have been a help to some extent.
I'm trying to rid my Expression Engine site of the index.php? part in my URLs using ISAPI REWRITE on IIS.
I've got [ISAPI_Rewrite]
RewriteRule (/(?:site|member|search|Pd{1,8}).*) /index.php?$1 [I,L]
which removes the index.php but not the? part.
we're using IIS 5.0 which doesn't have any flexible support for rewriting URLs which include parameters (AFAIK, anyway). We're currently testing an ISAPI Rewrite Plugin, which emulates the syntax and behaviour of mod_rewrite, which is why I felt this forum category to be the most appropriate for this post.
Our URLs at the moment look like:-
[url]where 'hg' is an instance of a key. In this particular example, we wish to rewrite our URL to read [url]homegarden' where 'homegarden' is a value of that respective key.
Since the value 'homegarden' isn't present in our current URL, we need some way to associate this value with it's relevant key, by mapping one to another. The ideal solution in this case would be to use RewriteMap, however the ISAPI plugin doesn't support this directive.
One other solution, that I've seen here is to use the 'homegarden' value as the key instead. However, due to the lack of flexibility of our system, this isn't possible.
Another method of achieving this is to hard-code a RewriteRule for every instance of a key, but this solution has obvious performance drawbacks (we have around 400 categories)
So, at the moment I'm out of ideas, which is why I thought I'd try and rack your brains for suggestions. An ideal scenario would be to use something like RewriteCond (which is supported by the plugin) to attach a file which would contain the key/value map.
The current supported directives are :-
RewriteRule
RedirectRule
RewriteHeader
RewriteCond
RewriteLog
RewriteLogLevel
RewriteFilterPriority
IterationLimit
MaxMatchCount
StrictParsing
Even if it's not possible using one of the above, maybe someone can point me to solution involving a method other than using this particular plugin?
Since about 2002 I have constantly had my own co-located and then dedicated box. Before that, the only paid host I ever used was verio.net. Now that I sold off most of my sites, it is time to move to a smaller, shared hosting plan.
My question is can anyone suggest a good hosting plan? I do not need a lot of space or bandwidth, but I do require a few things:
- ASP.net 3.5 is a huge plus, but 2.0 is do-able
- At least one msSQL database
- Daily backups is also a huge plus. I don't need this second, but eventually I will want it.
- Good technical support is a must. I have dealt with to many companies even with my dedicated hosting that offered horrible tech support. A three day wait on a question is not acceptable. Phone support is a plus, but a 24 hour reply on an email is enough.
- ISAPI-Rewrite, or an equivalent is a must. I rewrite my URL's for SE rankings, as I believe everyone should, so the ability to host a rewrite script is a must. Though I use ISAPI-Rewrite, if their is an equivalent that is do-able.
- Need to be able to run at least (2) domains. My main company domain and then a second domain which is basically a landing page. In future I need a 3rd domain added, so ability to upgrade or add on a domain cheaply is a must too.
If you own a hosting company that matches this, or can suggest any please do so. If you suggest and they offer a referral program feel free to let me know your referral code as you obviously deserve the credit for suggesting the company.
I'm using IIS 6.0 and an isapi dll created in Delphi, and I'm getting an error which I cannot understand.
At some point when I make a request for this file I get an error in Firefox ("The connection to the server was reset while the page was loading"). At the same time http error log is full of "Connection_Abandoned_By_AppPool" messages. After this happens, there is almost nothing I can do - I tried recycling the application pool, then I tried restarting the IIS server, and finally I reset the computer - NONE of this helped.
The only thing that resolves the issue is to recompile the dll and replace it (the source is absolutely the same). After that everything works fine.
I have a separate App pool for this dll (not executing in DefaultAppPool). At first, I thought that the problem lies in "Rapid fail protection" so I have disabled it, but the problem hapenned again.
The biggest issue is that this problem hapenned exactly 4 times in two months. It's very rare, and very hard to debug.
Finally, I have discovered on thing that could lead to the solution (with somebody's help :-)). I have enabled recycling for this pool every 2 hours. Looking at the event log in windows, I have found out that the problem always occured after the pool was recycled. So, each time this problem hapenned I have this logged in Event log as an information message:
"A worker process with process id of '2312' serving application pool 'PromjenePool' has requested a recycle because the worker process reached its allowed processing time limit. ".
After that, in my log there is a series (hundreds, thousands) of error messages, two or three in a second, first of them coming just a few seconds after information about recycling. The warning messages are like this:
"A process serving application pool 'PromjenePool' terminated unexpectedly. The process id was '2604'. The process exit code was '0x1'. "
The first thing that my dll does is that it logs that it has been initalized to a log file. After this happens, there is no trace of initialization in my log file. So, probably dll is never loaded, or it crashes when it tries to open the file.
So, to resume, I have recycle periods of 120 mins, and about 300-400 recycles happen without any problem. After one recycle, I just keep getting error "The connection to the server was reset while the page was loading", httperr log contains loads of ""Connection_Abandoned_By_AppPool" messages, and event log is logging that process serving my pool is terminating unexpectedly. The most bizzare thing is that recycling the dll, restarting iis or computer won't help, the only thing that surely helps is to recompile the dll (same source).
Just to add - if it can help - all dll is basically doing is connecting via TCP sockets to a data feed, constantly reads data and publishes it through dll. There is no connection to database, just sockets and appending messages to local file.
I am talking like a few thousand sites per server (actually a pair that act as a unified server, routing for load balancing). In a muli-thousand site IIS server, will having ISAPI Rewrites enables for ALL of the IIS virtual sites cause performance to degrade?
View 1 Replies View RelatedToday on a server of mine mysql keeps crashing and I need to manually restart it over and over, the load as well keeps spiking quite high until I stop mysql for a few minutes. There isn't a extra load of traffic or anything as I have the same amount of users on several other servers doing more then this one.
How do I tell exactly whats happening from then how would I go about fixing it?
Basically it mysql crashes and needs to just be manually restarted via ssh.
My web site keeps crashing for some reason like every 10 minutes. The site will be up for 10 minutes and then down for 10 minutes. Up for anotehr 10 minutes and then down for another 10 minutes.
The odd thing is that the server does not crash, the site itself does. I can access WHM during these periods of downtime and WHM says everything is perfect. All green check marks, low server load, low memory usage. Everything looks perfect.
On top of being able to access WHM during these periods of downtime, I can even access that green page from the IP, 123.456.789 (exampe ip) that says "Great success, Apache is working on your WHM/Cpanel server"
(this one: img34.imageshack.us/img34/749/greatsuccessw.jpg)
But as soon as I put in my account name after the IP (like 123.456.789/~account), the site crashes. And by crash I mean it goes super slow and then times out.
I don't understand what the problem is and the managed solutions support that I have is usually really good at this, but is also having trouble with this problem.
I'm not sure if this is relevant, but incase it helps I have vBulletin forums and a mySQL database backend. Also, the dedicated server is a linux server with Centos 5.3.
I keep getting a segmentation fault after a few hours when I leave lighttpd on. It doesn't seem like much resources are being used and its serving about 60mbit/s. There's nothing in the error or log file.
I'm using CentOS 2.6.18-92.1.13.el5
and
lighttpd-1.5.0-r1992
Here's the config:
server.modules = (
"mod_access",
"mod_trigger_b4_dl",
"mod_status",
"mod_proxy_core",
"mod_proxy_backend_fastcgi",
"mod_uploadprogress"
)
upload-progress.progress-url = "/progress"
server.network-backend = "gthread-aio"
server.max-fds = 15000
server.max-connections = 10000
server.event-handler = "linux-sysepoll"
I've actually been having this issue since I've moved to lighttpd 1.5, 1.4 was working fine but I need the features in 1.5. I've tried changing the event handler and network backend to no avail.
How can I at least find out what's causing the error?
I've experienced two episodes of cPanel/WHM not loading or working twice within the past 2 weeks.
Suddenly cPanel/WHM fails to load, but web service, provided by Litespeed (only installed today) continues to serve and mysql is unaffected, just cPanel/WHM.
System specs:
Intel Celeron Proccesor
256 RAM (yeah I know...)
Debian Etch
Joomla! 1.5
Okay... so, here goes.
Recently, I have switched from Siteground hosting services and everything was fine. Now I have changed over to a dedicated server that resides at my house. I'm routing DNS through FreeDNS (freedns.afraid.org).
For a week or two, the server was fine. Recently, we started working on the website on the new server (posting new articles, changing the theme, adding some plugins, etc.) and it's steadily gotten worse and worse about, when we save changes to something, or post an article, the website will go offline. Eventually, the website will come back.
My question is: What is causing this? The actual server isn't shutting off, so It has to be something between my modem and the user. Is my modem just shutting off because it's overloaded? (that seems sort of improbable) Or, is it a DNS issue? (I have a Dynamic DNS system set up that is working fine)
My server keeps crashing and this is the last log. Can you help me to find out whats the problem here.

I cannot figure out why my server is always dead when i wake up most mornings.
I am trying to figure out why my server is crashing nearly every night between 12am and 9am eastern time. When it crashes it is down all night until i wake up and have to reboot the damn server. I am wondering if cron jobs are taking up alot of the cpu or something because the server load isn't that much. here is my specs:
Server:
Softlayer
2 CPUS - dual core xenon 3.0mhz
500gb hd
2 gb DDR memory
Softare:
WHM/Control Panel with Ipanel back admin
Sites:
I am currently hosting 4,500 sites on the server.
The server load usually stays below 1 and is blazing fast. I just cannot figure out why it crashes when i sleep. I dont know if there is a virus or what. PHP mail is disabled so there would be no spamming crashing it. Here is my cron jobs:
17 2 * * * /scripts/upcp
0 1 * * * /scripts/cpbackup
*/15 * * * * /usr/local/cpanel/whostmgr/bin/dnsqueue > /dev/null 2>&1

*/5 * * * * /usr/local/cpanel/bin/dcpumon >/dev/null 2>&1
I dont know much about cron jobs as I am new to this server hosting thing and just bought an established company. Maybe one of the cron jobs is causing it to crash in the middle of the night?

sv03 kernel: Recursive die() failure, output suppressed
I have a FreeBSD server with Cpanel. It keeps crashing every few hours. Data centre swapped RAM, Chassie but no luck. Hard Drive was scanned and no errors found. I can't find anything in the logs (/var/logs/messages). Which direction should I be looking into?
View 10 Replies View RelatedI run a drupal site on a VPS running Lighttpd with 128MB ram and 15GB disk space. Every so often the server crashes and I have no access to even reboot via the shell, I have to get my host to reboot the VPS. They say its most likely due to the server running out of memory. I would have no more than 5 users plus 5 guests online at the same time. So my question is this...
How can I find out exactly what is consuming the memory and causing the server to crash? I have looked at drupal logs and the server logs, but I'm no wiser as to whats causing it. What should I be looking for and what can I do to try and solve this?
One of my servers at FDC Servers is crashing (= kernel panic) every few days since we got it.
The specs of the machine are:
C2D E6550, 2 GB
Linux .. 2.6.24.4-64.fc8 #1 SMP Sat Mar 29 09:15:49 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux
I opened several tickets with FDC, after running memtest and clocking down memory they say it's not a hardware issue but software related.
Quote:
I see that according to this ticket, memtest has been run without error and the memory was even slightly clocked down to avoid problems. It appears that the errors you are reporting are software related...
I already tried several kernels and different application versions.
The server is only running lighttpd.
I've been running 3 Xen servers for the last few months in a production environment, and facing a strange problem with one of them.
Server 1 and 2 run a couple of DomU's and are running just fine.
Server 3 runs one DomU and takes care of all the backups for the DomU's of Server 1 and 2
The DomU on Server 3 is crashing every night, right when the backups are being made.
DomU becomes inaccessible, but keeps appearing at xm list with state ------
When I try to connect to the console it wont let me connect. The only way to get the DomU back up is by using xm destroy and xm create again.
For the back-up I use NFS where the DomU on Server 3 is the host, and the other DomU's of Server 1 and 2 connect to it through an internal bridge.
Below you'll find some information about Server 3:
