An exception

[arabin]

I am trying to send messages in a loop. Here what I get on a certain iteration (after several hundreds of successes):

What does it mean?

There's no need to open a new thread. You have already one.

Whats ur setup for Jboss? Is it all on a linux/windows box?
I suspect all your exceptions to be IO Related(or thats what the messages say).

Here it is without new thread. 9xx sendings were OK this time. After that I have a problem.

I have windows xp machine. Another windows xp machine works fine with loop up to 10000 messages (did not test more than that).

That was McAfee. The problem is solved.
