Folks:

I'm cross posting this to both JAVA400-L and MIDRANGE-L, as I think it might not be specific to Java.

I've got a java application that's running on a customers system that is periodically spiking in it's cpu utilization.

The really odd thing about this is that an ENDJOB OPTION(*IMMED) takes a long time to kill the job ... sometimes hours.

I had them do a DMPJVM on the application and all the threads were either sleeping, waiting, timed wait, or java wait. I can't figure out where the cpu utilization is happening.

Any ideas?

Thanks!

Is this on V4.0? When it was new, there were issues with releasing
objects locks. I vaguely recall having to use endjobabn a few times.
There were PTFs.
