How can I see which script is causing problems/high load

[SubZero]

Hi

I see that a user is using so much resources. I have suexec enabled. But I can 't exactly see which script (and which exact request) is making this high load and causing problems. Can anybody point me to a direction?

Try to kill a script and then run everything as usual, if load average goes down that's the one.. and if you have more than one, go rotating those steps until you find wich is.

The processes are PHP processes. I can not catch them myself :P
