Apache Crashes When Trying To Upgrade
May 20, 2008I tried to upgrade from apache 2.0.51 to 2.0.63 but it crashes as soon as new version is started and httpd is reloaded.
here is a part of the log

I am on VPS and myself am quite a noob in this. Upgrade is performed by the support people.
If you guys can help please explain in lame terms
Let me know if you need some specific info about the system.
I was suggested that some modules might not be upgraded yet and they cause the crash, so to fix I should remove modules one by one from httpd config until get to the problematic one.
Apache Crashes And Does Not Restart; Every Day
Jun 27, 2007I am running CPanel and WHM, and every morning, I need to restart apache manually in order to work. Then it works for the whole day. It crashes I guess, but I don't know why. What logs do I need to check?
View 9 Replies View RelatedApache Crashes (or Does It?) Every Hour Or So
Dec 16, 2007I've been trying to see whats going on with this server for a few days now but am unable to resolve the issue.
This is a 3 server setup. One is a mail server, another a mysql server and the host server. The apache on the host has plenty of ram (8 gigs) and it is currently under 5 gigs. The site is mainly a social networking site.
Now the apache would crash at times like 1:16, 2:17, 3:16, 4:18; basically in 1 hour intervals. Now it doesn't always crash every hour. Sometimes it might go up to 5 hours and may crash at say 8:50
Well it turns out that the mail server new mass mailing method has some sort of effect on the host server.
This is what happens.
1.) Host has a ton of apache processes up and running (site is fine and dandy).
2.) Mail server is about to launch its barrage email (load about .5)
3.) Then all of the apache processes stopped appearing on my top (nobody is able to browse the site at this point).
4.) after a few minutes the apache processes reappear and the site loads again.
5.) Mail server is now mass mailing and its loads reaches up to 4.
6.) WHM emails me that apache was down and it restarted the service.
Here is the interesting thing about this. First of all I found out that the apache processes were actually not gone. They were somehow suppressed. For example during this freeze moment, if I run a "ps aux" I see that all the apache process are running yet they are not using any cpu or ram (which is why I don't see them on top). Now if I were to do a "service httpd restart" during this moment, it will restart but will still be frozen until its set time.
When the site is accessible again, that is when the mail starts leaving from the mail server.
The owner thinks this is related, and I tend to agree.
The only problem is that I have no clue as to what is going on. Apache does not leave any error logs period. Nothing in messages or in exim logs. For a while I thought it might be lfd killing the apache but I was wrong. Nothing informative on the lfd logs either.
Could it be perhaps a bind issue? Somehow the mail server takes over the host system before its launch?
I'm posting this in the hope that some of the techies here and give me some hints and directions where I can find an answer. Perhaps someone who read this thread has seen this kind of issue before.
Apache :: How To Examine Server Crashes
Mar 7, 2013I'm using mod_perl 2.0.7 on Windows with Apache 2.2.23. I got Apache from Apachelounge, and compiled mod_perl and perl 5.16.2 myself using Visual Studio 2008. I'm using a 32-bit Windows Vista.
Pretty frequently my app (which works just fine on Linux) makes Apache crash. If I perform 500 requests with Apache Bench, I see this:
Benchmarking localhost (be patient)
Completed 100 requests
Completed 200 requests
Completed 300 requests
apr_socket_recv: An existing connection was forcibly closed by the
remote host. (730054)
Total of 338 requests completed
In the apache error log I see apache is restarting, but this results in some HTTP 500 errors that make the apache-bench results fail. When using a web browser, I also get these http 500 errors.
If I run the application using native CGI (i.e. I turn off mod_perl) I do not see crashes but of course it is *very* slow.
How can I find out what makes apache/mod_perl crash?
I asked the same on the modperl mailing lists, there they said I needed the symbol files for apache (*.pdb files). Where are these?
Apache :: Service With Automatic Start Crashes
Nov 22, 2013I encountered a strange problem when installing apache 2.2 or 2.4 as a service and set the service to be automaticly started.On restart of windows, apache service crashes with an access violation.

Apr 16, 2015I've got a problem at a local customer with rotatelogs.exe and the current release of Apache HTTPD 2.4.12.
I've downloaded the 64-bit zip-file (VC11) and installed the VC11 vcredist in both 32- and 64-bit version.
The project is to upgrade apache 2.2 to apache 2.4. I've adjusted the configuration and added rotatelogs for log rotation for error_log and access_log.
The configuration is 100% correct, I can copy the line to cmd.exe and it runs correctly.
Variables are set in global environment, APACHE_HOME is set with "/" instead of "" to get sure rotatelogs.exe is found.
CPanel Crashes My Server
Aug 8, 2008I have remote uptime tracking on my server, and I am regularly getting text messages and emails regarding my server going down. This in itself isn't odd, however the fact is, everytime the problem is cPanel.
I log into my PC and find an email from my server and it contains the following;
Quote:
cpsrvd failed @ Thu Aug 7 19:11:17 2008. A restart was attempted automagically.
Failure Reason: Unable to connect to port 2086
what's causing this? It's on a VPS and the main server hasn't been down once, but this VPS constantly goes offline, at least once a day...
Got Tired From My Server Crashes
Mar 2, 2008I have a server ($200)
I got tired from these frequent crashes.
I do not know how companies promising 99% uptime while customers do not get 80% uptime.
Just see this snapshot
Every week my server is down at least twice.
I have 7000-8000 daily uniques.
I really got tired.
Got tired from life also.
Which Logs To Check If Dns Crashes
Mar 30, 2008I have a VPS and almost once per day PIM has to restart the DNS service. I think it is because of the high volume of sites on it.
Could someone point me to which log files I could have a look at and maybe get a clue why it crashes?
Quotaon Nearly Crashes Server
Jan 10, 2008I have seen this on a few different cpanel servers. Mainly seems an issue with some kernels but I have a server at softlayer and it seems it does it after a server has been up a few days.
At first I thought this was just an issue with grsecurity kernels but seems its an issue with any kernel on it after it been up a few days. On other servers though I have been able to change kernel versions and fix it. I suppose this may be related to disk space used as well.
Problem with my softlayer server is that teh tech didnt follow my partitong directions and installed everything in one slab / so I guess when you edit or add quota it has to scan the entire disk.
I had recently rebooted that server into a 2.6.29-grsecurity kernel and it fixed the issue but tonight I was messing around and it started all over. Not as bad as before but still around 305 minutes of totally lagging the server.
My mount options are
LABEL=/ / ext3 defaults,noatime,usrquota 1 1
Seems to do the same with or without noatime.
Has anyone ran into this issue or know any solution?

How To Prevent OOM (Out Of Memory) Crashes
Aug 19, 2008I have a colocated server with the following specs:
Intel Core 2 Quad Q6600 2.4Ghz
4GB RAM
400GB SATA Drive
I have a problem every few days, the server keeps hanging up and giving an "Out of Memory" message and SSH just hangs and doesn't connect. Every time i have to call out a tech to manually reboot it.
Is there a setting i can change to make SSH connect even when it is out of memory, or anything that can prevent it happening?
Server Crashes Every 600 Seconds
Feb 13, 2007Today, I put a new server on our racks.
Problem: the machine crashes exactly every 10 minutes. The crash occurs with no entry on the logs and with 0.00 load. It is as if someone take out the current every 10 minutes.
Here are the specs:
- 2 CPU Intel Xeon 2.0
- 8 Gb RAM ECC
- 2 x 250 Gb HDs
This machine needs plenty of current. I wonder if I am not going over the rack power quota. May be there is a system to allow overages for then 10 minutes, then it cut back the current to the rack quota.
Server Crashes Around Same Time Each Day
Nov 26, 2007I have to reboot this server each day. It seems to crash (or freeze if you call it) around 11:55 pm server time (central US). How do I trace the cause of this? I installed CSF / LFD in replacement of APF/BFD.
This is a centos 3.9 / cpanel 11 box.
crontab -e shows nothing out of the default ordinary
/var/log/messages shows this

Strange Server Crashes
Apr 27, 2007I got a new server (Debian Etch) and experienced 2 strange server crashes during the last month.
When it happends, I can ping my server, but I can not login and all services are down.
After reboot log files doesn't show anything unusual.
There are only 2 small html sites on this server with 10-20 visitors per day.
MySQL Crashes: Might Be Because Of Memory
Jan 5, 2007My mysql server keeps on crashing. I wonder if it is because of out of memory. Last week, I upgraded my memory from 2GB to 6GB and I executed the command "free" to check memory usage. It uses 5GB in memory usage and leave under 10,000k unuse. Do you think this might be the cause of weekly mysql crashes?
I only use the server for mysql, so it is a dedicated mysql server.
[Interworx] My VPS Crashes After Making A Backup
Dec 8, 2008I have a VPS with Linux and 128 MB RAM and the Control Panel is an Interworx one. Backups are made with SiteWorx (a panel within NodeWorx, and only visible one for Shared Host customers).
- The VPS is working properly the whole day;
- The content of my VPS (besides the necessary software) is a PHPBB 3.0.0 forum that is heavily visited. Its subject is World of Warcraft, a popular MMORPG;
- Making a backup is successful, and I am reported by the system that way by an e-mail which also reaches me;
- Shortly after that my VPS crashes and stays offline, until I can restart it or my webhost notices that it is offline. NodeWorx and SSH are inaccesible. As soon as I can access the SSH I can restart MySQL server and everything is working properly again.
I suspect that 128 MB RAM is too little for my VPS backups.
Server Regularily Crashes And Goes Offline
Aug 24, 2008I have a dedicated server with burst.net and it's been pretty good, well, it was, but more recently I've found it seems to be crashing every day, at least once. On the server I have created 2 VPS's, both have cPanel installed, however every day I am receiving emails from my server telling me that cPanel has crashed and the server has to have been rebooted, which seems odd.
I've contacted cPanel support before, numerous times now and everytime they tell me that they're looking into it, they update cPanel but the problem persists.
has anyone got any experience with this?
Server information:
2048MB Ram
2.8GHZ processor
centOS 5
hyperVM
Each VPS Has 1024mb ram assigned to it, and it doesn't seem to be a problem with ram that is causing it, because the VPS's never use more than 200MB of ram each. Each VPS was created in hyperVM with the "OpenVZ" type selected. Could there be a problem with my server, as in, hardware, or is this a software problem? Has anyone been through this experience before? I'm mighty confused about what's going on.
Exim Mail Queue - Server Crashes
May 21, 2009Today my server started to go off-line and each time i restarted it went down within couple minutes. So i looked into it and found that i had over 7000 emails in Exim Mail Queue. All of them are spam. I deleted them through WHM and now everything seems good again but....
My question is how can i check what caused this problem? Has one of my domains been compromised with and sending out spam? What can i do?
Windows Application 2003 Crashes On RAID 5 Server, Can I Recover Data
Jun 12, 2007Windows Application 2003 crashed on RAID 5 server, we tried to take the NTFS files from the hardrive and mount them on a knobix which was booted from a cdrom drive. Knopix could read the files but it was unable to mount them I guess for compatiblity reasons.
Is there anyway we can get a backup of that ntfs file and restore our data?
Creating Daily Backups
Mar 30, 2009I want to set up my server (a linux dedicated server) to automatically create daily backups of the pop3, mysql, & webfiles. I want it to go to a server which i have purchased with the exact same specifications.
I am not very good at unix command line/scripting. So what I need is for someone to help me define the backup strategy, select the scripts, and tell me of how to make sure backup server is secure.
Daily Attack From The Same Network
Apr 8, 2009Our website is receiving a daily attack from a french network called Neuf Cegetel. The IP is different each day but the network is always the same. The attack is daily and during several hours.
The website does not use ajax (the request is an ajax request) and there is no URL /0_0?_=... But the attacker use a random URL similar to this /0_0?_=1238873869634. Since the URL is always different the page is not cached so it is compressed by mod_deflate and therefore the attack is more harmful. The User-Agent and the cookies changes quite a lot but it is always an ajax request. Taking in account that it is the only ajax request in the server that would be the easily way to stop it. But it seems that when we try to stop the attack, the attacker try another way, what makes me think that the attack is voluntary (not a virus nor something like that).
Since it seems that the attacker can be easily found it (we are a Spanish website and the attacker comes always from the same French network), should we report this? If it were a virus in a remote server, the solution maybe is just to contact the abuse department of the network but if it is voluntary I think that we should discover who is behind the attack since it might be a company that want to bother us, a competitor or something like that. What do you think?

HostV Daily Load
Aug 27, 2008customer of HostV's VPS hosting, and for the past 3 days, at almost exactly 01:20 GMT, CPU load jumps from an average of about 0.10 to 2.5+, stays there for over an hour, then drops back down.
During this time, there are NO processes on my virtual server using any significant amount of CPU time, memory, or IO. No cron jobs are running on my server, etc.
Note the output from 'uptime' below (I was monitoring it waiting for the problem to occur, which it did at exactly the time I expected):
00:32:05 up 22:01, 2 users, load average: 0.09, 0.11, 0.08
00:32:07 up 22:01, 2 users, load average: 0.08, 0.11, 0.08
01:09:49 up 22:39, 2 users, load average: 0.06, 0.03, 0.00
01:10:03 up 22:39, 2 users, load average: 0.05, 0.03, 0.00
01:19:26 up 22:48, 2 users, load average: 0.46, 0.16, 0.04
01:20:42 up 22:50, 2 users, load average: 1.53, 0.55, 0.18
01:21:39 up 22:51, 2 users, load average: 1.40, 0.67, 0.24
01:46:04 up 23:15, 2 users, load average: 3.06, 2.02, 1.52
Also note output from 'top', taken when load average was at 3.06 shown on the last line above:
Cpu(s): 0.1% us, 0.0% sy, 0.0% ni, 91.0% id, 9.0% wa, 0.0% hi, 0.0% si
My cpu usage is very low (0.1%) but wait time is at 9.0%, and I've seen this go as high as 70% during these times.
So, basically, there is a problem that exists on the host node somewhere that is causing my site to become effectively unresponsive (page load 20 seconds+ - measured), and it happens every single day at the same time.
So, why am I posting it here instead of logging a trouble ticket? I have logged a trouble ticket, but when I encountered the problem yesterday, despite logging it as "CRITICAL", I had to wait nearly 5 hours for a response, which effectively said not much beyond "we noticed the problem and fixed it and we're monitoring it". So I don't have a lot of faith that today's response will be any better.
I moved to HostV because of similar problems I was encountering with shared hosting, and was assured before signing up that the kind of problem I'm seeing doesn't happen. So now I'm outlaying more than 10 times the cost for almost exactly the same problems and a similarly unhelpful response to it.
By publicly posting the problem, I would hope that someone at HostV will ensure the problem is addressed PROPERLY, rather than bandaided again, and that hopefully we will all be able to see just how good HostV's support CAN be (as evidenced in another similar post).
I await HostV/Cirtex's response.
As shown in the uptime information about, server uptime is 23:15, because I rebooted the virtual server yesterday to see if that helped. It didn't. In fact, it took over 20 minutes for the server to come back up, which is why I'm not going to do it again.
Daily Hacking Attempts
Oct 13, 2007Our VPS is being hit several times a day with hacking attempts. We have been actively monitoring error logs and can see the failed attempts. I was just wondering if there is a better way to track such attempts or another system log that wold provide additional info on these attacks? or maybe some 3rd party logging scripts?
View 13 Replies View RelatedRAID-1 Vs. Daily Backups
Mar 7, 2007I just had a quick question about backup solutions. What advantage would I have by setting up 2 HD's in a RAID-1 array as opposed to just doing daily automated backups on one of the drives.
The way I see it, if I have automated backups, HD use for that backup drive is limited to say 20 minutes a day. In a RAID-1 array however, both drives are used at the same rate. Wouldn't this provide better life expectancy for the backup drive, granted it is at the expense of having a guaranteed instant replacement for that original drive?
Reason I'm asking is because I'm setting up a Mac Mini for a friend as a web server and he would like to have data backups. The only way to add space is to intall an external hard drive so my options are a bit limited.
Backup Daily Contrab
Jun 2, 2007i want to run /scripts/cpbackup every day begain with 12:00 AM and i put this line in /tmp/crontab.XXXXwuxGUI File
0 0 * * * /scripts/cpbackup
but the backup didn't work and do the job
Mirroring Live Drive Daily?
Mar 22, 2008I would like to create an exact copy of my live drive on a daily basis via cron. Is there a good mechanism for doing this *without* taking the main drive offline? It seems like the two common backup solutions: dd and rsync both have issues in this area. I don’t think Rsync can create an exact mirror (including partitions) and dd looks like you need to unmount the drive(s) first.
Both drives are of identical size and installed via the ide controller.
Daily Dozen LFD Blocks Normal
May 5, 2009I recently got a dedi from Hivelocity, and they installed CSF/LFD. On my previous hosts, I didn't have this, just cPHulk. With this dedi, I'm receiving nearly a dozen daily emails from LFD with IPs that have been blocked for multiple failed logins, mostly with username root, but also sales, staff, admin, system, etc., and a few for port scanning.
Is this normal? I've already disabled direct root login via SSH, and I'm not really worried about anyone actually managing to gain access, I'm just curious about the high number of attempts. On previous hosts, where I actually had active sites and forums, with links posted on other forums that are indexed and nicely ranked by Google, I rarely received any emails from cPBrute at all.
Limit User Download Daily
Jun 22, 2008Is there any apache module which can limit user download daily. e.g. userA can download XX GB per day.
I am using mod_cband but it seems it can't do something like that.
