Take a thread dump (QUIT signal on *NIX, CTRL-BREAK on windows console,
jstack in recent JVM implementations, ... some monitoring programs have
this ability, too) and look at what is running. You may have to run a
couple of them and compare. The thread that is always running the same
thing is likely to be the one that is causing problems.
