Working condition: Server 2008 R2
Server: Apache 2.4.9 (Win32-VC10) as reverse proxy - same configuration as before
Since the change to apache 2.4.9 we discover 5 log-entries for one sync-process via mobile device where before (2.4.7) there have been only 3 entries for the same sync-process with the same device. Besides this it takes a bit longer.
The server is going down from time to time, every 12 days or so the site hosted there is no longer accesible, everything starts with the site slowing don and down and then is not longer reachable, what we do is to request a power cycle, and with this we start all over again till next power cycle, so on so on, of course, here are my server details and more info on this:
- MySQL - 5.1.41-3ubuntu12.10
- Apache - 2.2.14-5ubuntu8.4
- PHP - 5.3.2-1ubuntu4.9
- operating system: Ubuntu Server 10.04 LTS
After some time emailing the support guys to barely check about what's going on, we received an email with a few things:
1.- found a few errors that likely would cause issues with Apache. The first error is:
[Mon Feb 04 05:03:10 2013] [error] mod_fcgid: fcgid process manager died, restarting the server and the next error is:
[Mon Feb 04 14:32:34 2013] [error] server reached MaxClients setting, consider raising the MaxClients setting ...
Both these errors seem to indicate that you have a process that is running out of control on your server. We were unable to determine what script on your site is running caused your connections to be maxed out however it does appear that before these errors were generated there was a WordPress plugin referenced in your access logs...
2.- Additionally during our review we did find that your error log for mercadodedinerousa.com is 45 GB's which is excessively large and can cause problems when Apache is trying to write a such a large file.
3.- The majority of the errors being logged are:
[Wed Feb 06 12:12:31 2013] [error] [client 200.76.90.5] Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden: /var/www/vhosts/mercadodedinerousa.com/httpdocs/index.pl, referer: [URL]
I have a web and database server (on a Cartikahosting clustered shared Windows host) that provides gift and fleet card authorization to various desktop clients I have throughout the USA and Canada. The database is MySQL and my site is written in ASP.
Even at 99.9% uptime I still have significant problems with downtime and when my site is down, none of my customers can use their prepaid or fleet cards to buy services. Over the past six months my web server has gone down or the database server has had problems, such that my site has been down at least once a month for enough time that my customers have complained to me.
I have decided to add a second authorization server (on a Jodohost shared host)such that if my clients try to reach server1.com (not my actual site, example only - I will provide my site name in private messages only) but server1.com fails to respond, the desktop clients will try to use a second server I want to set up at Jodohost server2.com (also example only).
Is it possible to set up real-time database syncing / mirroring such that I can actually have two redundant servers without running the risk of the servers becoming unsynced?
Any other process or configuration you would recommend? Even moving to a dedicated server won't guarantee me 100% uptime, and my thought that having two independent 99.9% uptime servers would virtually guarantee me 100% uptime if I could get the configuration and set up worked out.
everytime I modify a plan (having subscriptions or none) and press "update and sync", the plan starts syncing and never stop. I let the plan syncing three hours today and the result is the same, trying to disconnect/reconnect and still syncing.

The Goal:Have Plesk Accounts on it's server be able to sync to an external SmarterMail server, rather than installing SmarterMail on that same serve (which seems to be available natively).
We run httpd-2.2.3 on CentOS 5.8 with caching enable. The server has been running for 4 years, but htcacheclean has never been run. The cache folder is about 10GB now (a "du" on the folder takes a very long time to complete). Should we expect any problem when running htcacheclean for a first time such as server slowing or freezing, ... Furthermore, in case of freezing, if we disable caching and restart the server, do we expect any problems? We did a few test on our test servers, and everything was fine, but our test servers do not have a large cache folder.

View 11 Replies View RelatedI have a tiny "webpage" in an Apache server running on my computer. I've got for it this .htaccess file: URL...I have written it by googling,.(I don't really know very much about Apache HTTPD, but my Java suite requires this stuff, so here I am). Supposedly the first paragraph is to avoid Google Chrome from caching my files and the second part (the Order sentences) are to allow anyone to view only those kinds of files (which is otherwise let them see everything but folder roots.
And here is the httpd.conf, which I've modified almost only to change the listen port, the server name, and to replace the AllowOverride None into AllowOverride All so that .htaccess is actually used (I've deleted the comments for readability).URL....
I had never heard of something similar, "I can only load one instance of each file". In explanation, the only html file there's, runs from time to time a PHP script. Let's say I run it on localhost for example. Then everything is going fine. But I open a new tab, and load the same page (while the another one is yet open), and I'll get a 412 HTTP error. Similar thing happens if I try to load the webpage from another device. And, with my little experience with Apache HTTPD, I guess it's because of this .htaccess or httpd.conf files. Why does this happen or how can I solve it (either it be or not related to one of these files, I'll do whatever is needed)?
Apache 2.2.22 which can be found [link URL....]here[/link] in Windows 8 x86.
I'm trying to improve the performance of my website and noticed that https pages take really long to load:
[URL] ....
[URL] ....
It appears this problem is caused by using https, because when I open my site without https it loads pretty quickly.
[URL] ....
From what I can see it appears that the main problem is the time to first byte, so my question is how can I reduce this?
My virtualhost for SSL is set like this:
Quote:
<VirtualHost 46.249.47.12:443>
DocumentRoot "C:Program Files (x86)Apache Software FoundationApache24htdocssite 2"
ServerName www.elitegameservers.net
ServerAlias elitegameservers.net
ErrorLog "logs/xgclan.com-error.log"
[Code] ....
I have replaced the real paths with "PATH" for security reasons. How to reduce the time to first byte in general. I tried setting up memcache to accomplish this but I didn't notice any changes...
This is my mem cache config:
Quote:
<IfModule mod_mem_cache.c>
CacheEnable mem /
MCacheSize 10000000
MCacheMaxObjectCount 100000
MCacheMinObjectSize 1
MCacheMaxObjectSize 262144
</IfModule>
Update: Just ran the openssl speed command [URL] ....
I have configure my Apache to create rotated logs for every periodic time. It worked fine with my local PC, but when it is being configured on to a server system, the actual error.log file is not being update, only the rotated logs are created. If i remove the Error Log command from httpd.conf for Error Log Rotation, again it works fine as usual.

We have many webservers in our environment, Few webservers serves static contents. In one application, we often change the excel file. Every day or 2 days once we will modified the excel sheet content. File name will be the same, only the content will be changed. We will modify the content of the sheet and upload through FTP to the docroot. After we done this if we access the application URL, its displaying the old content. Its takes time to reflect. sometime with in 3 hours sometimes after a day only reflecting. We are not sure what is the issue. we cleared the cache in browser and tried then also its showing the old content. We are using DNS,network load balancer, proxy between the browser and the webserver.
I tired accessing through FQDN, it showed old content, then i accessed through the LB IP it showed the modifed file. For testing i changed the content again and then accessed. This time even for IP it showed old content. Same i tried with the instance 1 IP and Instance 2 IP. On first time it showing properly but after i cahnged the file content and accessed it showing the old file I tried accesing from a different PC where we havent accessed before, there also it showed old content, SO i feel browser cache is not an issue.
We using Source subnet mask IP persistence in load balancer. I am not sure where the old file is cached actually. Will it be cached in Load balancer or proxy or somewhere in webserver. Just we are placing the file in docroot and accessing it in the URL
This is a rare issue i have on a RHEL 5.2 + cPanel server.

So, that is correct too..
But email arrives with -4 hours time, example:

I already rebooted httpd, exim, and imap server, and the server itself too.. and problem stills.
I got report from webceo that I have some issues. May someone help me fix this?
DNS Lookup: 0.22 sec
Connect time: 0.33 sec
Host ping: 0.10 sec
That mean too slow with the other sites!
I can't get access to a certain site. I always get the page with:
network time out - server at *** takes to long to respons. More people have noticed this and apparently it only happens to people with certain specific providers. And not all the time. Some times they DO get access eventy to they belong to the same ISP. So I guess an ISP isn't blocking access to it otherwise it would be permenantly/The site administrator insists that certain ISP's are blocking his site. He's hosting it on his own server. The domain belongs is registered at namecheap.com.
If an ISP is blocking this site (if that's possible?), that would lead to that 'network timeout' page wouldn't it?
What is the most likely reason for getting a timeout page anyway?
I have a dedicated server specs: AMD 3500+ 64 Bit CPU, 1 GB Ram, 160 GB Sata Drive. For 1 month, CPU load average reaches 40-50 value. This happens about 5-6 times in a day. When I stop httpd service for 30 seconds everything goes normal. I think this is not a DoS attack because it comes systematic, I dont believe no one makes this regularly except bots.
Maybe its a system service or a cronjob but it stops when I turn off httpd service?
How can I be sure about what's making this regularly load?
I also did set up a script which mail me when load average of system goes crazy and restart httpd service. But instant restart is not working to stop load increase.
I bought a new server ...
It had 2GB RAM, 2.8 GHz processor ,NIC fast Ethernet , 500GB HD.
Window server 2003 standard x64.
4 ip.
The ip ping but I cannot connect to server using remote desktop.
Is this problem related to firewall, or the network it self.
What if NO down time for VPS?
1. CPU (with Mainboard)
2. RAM
3. HDD
4. SMPS
5. others
with ALL things redundant
** currently my sites (on VPS) are down since couple of hours.. and God knows when they will be live again!
one day later, if I run the following command again, the command is same as the one run by the first time.
rsync -avz username@IP:/home/asite/public_html/ /home/asite/public_html/
does it mean rsync will just check and copy the newer folders and files from the last copy?
I have the same server for 3 years...Over that time I've been reducing the number of sites i have..
Is it time to downgrade?
The spec is below.... On a positive side It's been up for almost 500 days so it's reliable.
Would i be better with a high spec reseller account or a smaller managed server rather than spending $220 per month. I spend at the moment.
I'd even consider paying the same i pay now if i could get a faster more upto date server

this issue from networks (enotch) or from my ISP?

I'm just wondering what exactly "CPU Time" is, I have searched Google and checked Wikipedia but still do not really understand. The main reason this is bugging me is that MySQL on our database server seems to have a very high "CPU Time" usage.
This is the top part of the output from "top", with MySQL shown:
