[Catalyst] apache at almost 100%

[Octavian Rasnita]

Hi,

I use a Catalyst application under Linux, and I use to add and modify its 
modules.

Now I see that the server works very slow, and if I use the top command, it 
shows that the processor is used more than 95%.

I restart apache with
service apache restart

and the processor usage goes down to a much lower level, but then it goes up 
slowly until over 90%

Please tell me how can I discover which of the application's modules make 
this high processor usage occur (in order to repair it).

Thank you.

Octavian
