Thanks for your feedback.  I've actually had lots of experience in this now.  I did a lot of experimenting and learned some things.  Some of these things are probably obsolete with JBPM 5.1.  I see that a threading issue was solved yesterday.

Anyway, I was experiencing thread deadlocks when running lots of processes in the same knowledge session in lots of threads simultaneously.

So what I created a pool of knoweldge sessions.  I created thin wrappers for the work item handlers so I could pass into the work item which session an asynchronous work item came from.  When a work item is complete I grab the session from the pool, grab the work item manager and complete it.

I think the upcoming release will make the knowledge session pool obsolete.
