Nothing there of any interest; all the ones you showed weren't running and were therefore
not contributing to the CPU usage.

That looks like something you should take care of...

Is your webapp opening files (or sockets) and failing to close them?  Running out of fd numbers
will normally be fatal, and is almost always due to bugs in a webapp.

What's your exact Tomcat version, JDK/JRE level, and platform?
