Strange Issue With my server Plz Help

Server Config
1

Hello,

I am running dedicated server, well there is strange problem happening from the last couple of months, As I am using monitoring services from couple of websites so what I noticed is that after few days or every day I am getting emails from monitoring websites regarding the Connection Time Out Error, I myself verified it as when I receive the email I checked by opening website its keep on loading, I contacted softlayer support they increase the ServerLimit to 1000 and they also increased the MaxClients to 1000 in apache conf file.

Please let me know what is the cause of this issue.

Here is my httpd.conf file configuration

RLimitMEM 473479850
RLimitCPU 240
KeepAlive On
ServerLimit 1000
MaxKeepAliveRequests 100
KeepAliveTimeout Off
UseCanonicalName Off
AccessFileName .htaccess D
efaultType text/plain

and

<IfModule prefork.c>
MinSpareServers 5
MaxSpareServers 10
StartServers 5
MaxClients 1000
MaxRequestsPerChild 10000
</IfModule>

My server configuration is as follows.

Intel Xeon 2.4 GHZ Quad Core
4GB Ram,
server load average under 1%
memory usage is always under 30%
Hard Disk usage is less then 20%

Please suggest.

-Regards.

Dear TimIgoe,

That could well be why your noticing a problem then - if everything is sharing one drive, when that drive becomes loaded everything ends up getting backed up.

Its a problem I’ve noticed on single drive servers, small ones that have 2 drives I tend to suggest splitting up database and site on - i.e. /var/lib/mysql is on the second drive

Next time it does it, check top for ‘iowait’ - it is possible something is causing your server to back up disk requests until the point that it appears to be timing out, your load may not appear high at this point due to everything waiting on IO and not being able to complete.

What type of hard disk is in this server? IDE / SATA / SCSI / SAS? Any Raid?
