Hi guys,

We currently have a VPS running Cpanel on Centos5.

I've noticed that the CPU usage has been very high and have also noticed a number of processes that keep running from the user 'nobody'

The one that comes up in rows of around 7 at a time is this:
/usr/local/apache/bin/httpd -k start -DSSL

another two run by 'nobody are the following;
[httpd] runs 4 at a time and uses around 67% of the CPU per process
[sh] <defunct> runs a fair bit too.

I'm wondering if anyone has tips for preventing all this or maybe if someone can tell me exactly what they are doing as google is not bringing anything useful up.

Cheers
Adam.

The 'nobody' processes are Apache web server child processes serving HTTP requests coming into your server for domain(s).

Apache in a cPanel server runs as the user 'nobody'.

What is the VPS specifications ? Can you post the top 10 processes consuming memory and CPU using the command below ?

top -d2c

then later press M to sort the top processes by memory usage.

How high is the cpu load exactly?

Its gone down now for some reason however checking in Cpanel it shows the user 'nobody' has used 150.53% earler today.
