Hi, It'd hard to help with that little information -- the possible causes are many. Can you run Tomcat inside a profiler and see if that tells you where CPU time is spent? For something like this, at least initially hprof might be useful.
Another idea is to send a SIGQUIT when the CPU is at 100% to see what threads are going on.
