PHP5-CGI & CPU Load

[okercho]

Hi!

Yesterday, about 23.00 my server hungs. Today, it hungs again about the same hour.
I have my ISPCP server virtualized with VmWare Server, and I can restar it without problem, but today I have a TOP open in a ssh window, and I see a 98.00 CPU Load (Incredible!) and a lot of php5-cgi process open.

This afternoon, when I open a webpage, I see a high load in WA (disk access) and webs loads slowly, but before yesterday, I never see this problem (I'm using this server for 3 months without problem until yesterday).

Any Ideas?

I'm trying to attach a top capture, but I can't
