Tomcat consuming high CPU

Question

Tomcat.exe is consuming 75% of CPU. Is anyone having any idea why it happens and how can that be decreased?

I am using Tomcat5.5 & J2SDK v 1.4.2_12

Answer 1

All the answers cover how to do an exact diagnose, in addition I would add that, from my experience, a infinite loop in one of your applications is probably the culprit.

As J-16 SDiZ said, your best bet is to run the profiler to narrow down the problem to one application.
