Now after a while one of those apache processes is using 1.3 gig of ram.

I then trace the process as follows:

# ls -la /proc/13135
total 0
dr-xr-xr-x 3 apache apache 0 Dec 21 16:17 .
dr-xr-xr-x 180 root root 0 Dec 20 23:43 ..

But this doesnt reeally tell me what website is actually responsible for this, all these process look the same?

So how can I find out what site is using all my ram, other command maybe?

Thanks

what the environment? does it work with other programmes?

Centos in this case so redhat env.
