Hi,
this sounds strange, the event admin impl is using a thread pool, so
it's ok that the thread stays around after it has delivered the event.
It will be reused for one of the next events. The pool has a limit, so
you shouldn't get more threads than that limit.
I'm wondering what this has to do with CPU though? If you create a
thread dump are these threads executing something or really just waiting
in the pool?
Regards
Carsten
