I've seen something very similar (maybe identical), but I wrote it off to my
being an EJB newbie. I was using the Cart example and modified the source
code to create and destroy ejbs as fast as possible. It ranged from around
100 to 700 creates before it would hang. I didn't have the restart the
server and I could run several of these clients at once. They would always
hang, but never at a predictable iteration number.
