Server Overloading always

Hello,

One of my servers is overloading always.

Following is top output.

Why do you think it is your apache compile?

23% of your load is being cause by waiting on the hard drive. That snapshot may not be indicative of how it normally runs but I would watch the IO on your server. If it stays up high and nothing is wrong like a failing disk you should try to reduce the IO. One of the easiest things is noatime and depending on your drive configuration moving MySQL to another drive.

Its just because I am getting alerts like this

Account: XXXX
Resource: Virtual Memory Size
Exceeded: 103 > 100 (MB)
Executable: /usr/local/cpanel/cgi-sys/php5
Command Line: php5
PID: 1235
Killed: No

and

Current Configuration is

Option Configured Value
Default PHP Version (.php files) 5
PHP 5 Handler cgi
PHP 4 Handler none

Apache suEXEC on

That does not mean the server is overloading. You have a script monitoring how much memory everything takes up and apparently a cPanel php process is taking too much up for it. When you get it you should login and see if you are able to see what it is doing. It is something related to php and cPanel.

This is more of a CSF configuration issue than a cPanel server question.

See these as examples to the fix:

Another "Excessive resource usage: XXX" question - ConfigServer Scripts Forum
lfd: Suspicious process running under user - ConfigServer Scripts Forum
FCGI issues - ConfigServer Scripts Forum

Big_Bull, you are discussing two totally distinct and separate issues.

Now regarding the loading issue, I can help you get to the bottom of that
and also optimize your system where needed. There also may be additional factors such as things not being compiled correctly for your hardware, problems with your hard drive or controller interface, etc and I can help diagnose those issues as well.

Now regarding the second item you mentioned with the virtual memory
alert, that is more of a simple configuration issue with LFD (CSF).
