JBossMQ ThreadPoolFullException
Hi,
I'm running JBoss 4.2.1, with an external program delivering JMS messages to and MDB. The whole setup seems to run for a little while, but pretty soon, I start getting exceptions thrown, and after a few mins get the exceptions below. In the MDB I have a try / catch (Throwable) around the contents of onMessage in an attempt to stop any problems with my code stopping the Thread from being returned to the pool. I've tried upping the size of the threadpool, to no avail. I guess I'd like to know what circumstances would stop a thread from being returned to the pool. But mostly I just want to fix my problem ... any ideas ?
Many Thanks
Ed
