I now have a few thread dumps, but I'm not quite sure what to look for. I always have about 115 threads out of which about 33-38 are RUNNABLE. 32-34 are in state TIMED_WAITING, 32-34 are WAITING.
Correct me if I'm wrong, but I assume the thread or the threads that are burning CPU must be in state RUNNABLE and I guess, I will need to take take a look at a number of snapshots to actually catch the thread while it is executing.
In all of my dumps the GC Daemon is in state TIMED_WAITING (on object monitor), even though the machine is really busy. Does that mean it's not the GC Daemon?
What else should I look for?
I wasn't able to turn on GC logging on the production server, so I have no results from that side (yet).
Thank you for more help.
