Hi there, newbie here, first post!
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, this cannot be handled like that anymore so we need to find a solution, 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: http://www.mercadodedinerousa.com/autos/14741salon-internacional-del-automovil-2013-espera-el-lanzamiento-de-50-nuevos-vehiculos/
So, what you guys think it might be causing this problem? maybe is a good idea to take off all the WP plugins and check to see what happens? of just delete that post referred on point number 3?
Any help would be really appreciated, thanks a lot in advance!

There should be something like
| Code: |
<IfModule mpm_prefork_module>
StartServers 5
MinSpareServers 5
MaxSpareServers 10
MaxRequestWorkers 250
MaxConnectionsPerChild 0
</IfModule>
|
That needs to be adjusted to your needs.
Also the few files before "mod_fcgid: fcgid process manager died" shall be interessting. |
