Hi Valli. I'm using Fedora 8 Linux. I was going to suggest 
that you try and set the resource limits for the user the 
Apache PHP module runs as. This is probably the same 
user:group as the Apache web server.

So you will need to set this in the OS shell, probably as 
root user.

Then when the apache PHP module makes an OS system call, 
hopefully the limits you have set for the Apache user:group 
will apply.
