--------------------------------------------------------------
Hello All,

Trying to utilize JBoss 5.1.0 JMS server in our project. This is a standalone server without any clustering capabilities.
Running it as: run.bat -c default -b DTCJDBWFXJM1
The application with JBoss client tries to connect to the server and works pretty fine for 40-45 minutes.

After that I see an error message (see below) and the application is using fail-over functionality to reconnect to server again and it does.
I.e. the problem is resolved just by re-connecting again. I cannot say that this could be reproduced with some specific steps, but 
rather I see it sporadically happens under stress.
Unfortunately I cannot add any additional information from the server logs as soon as there's nothing unusual there - just a standard boot process.

One more note that potentially can give someone a clue. From time to time under stress again I see that JBoss just stops responding and delivering JMS messages to JMS clients, I'm not sure if that is cause by GC (stop the world?) - I'm using just a set of standard out-of-the-box configuration files with 5-7 JMS queues (all durable).

Would appreciate ideas on why this happens and how to workaround. Although this is not a big issue in DEV environment, potentialy It could be quite annoying to support people who receive e-mails every time some exception occurrs.

Here's Exception stacktrace:
