Is this a known issue?
Starting default configuration out of the box I see this exception:

I am looking into it.
But this is a production system that needs to be up all the time. Restarting JBoss is
bit drastic, as it kicks all users off and makes our app UI unavailable for a while.

Is it possible to restart JMS without restarting the JBoss server?
I'm using JBoss 3.2.3 and in some cases we run into a problem with JMS deadlocking.
Restarting JBoss server fixes the problem, but I'd like to be able to just stop and
restart JMS.
TIA

Here is the resolution of this issue. It turns out that we hit some weird
networking/Solaris problem between two specific Solaris machines. What happens is that
when the client on one machine disconnects from the server (running on the other
machine), Solaris does not cleanup the sockets.

One thing I noticed that when the connections start going bad this is what the thread

I have ReadTimeout set and it seems to work sometimes.
The problem seems to occur when I run clients over wide area network, which has many
delays and occasional errors.
Doing a simple kill -9 on a client seems to terminate everything properly. It's when
network hits occur that things can get m
We are testing with JBoss on Solaris and we observe the following situation. If the
client process is killed, the topic subscriptions are not getting cleaned up and
others who publish on this topic fill up the queues.

I forgot to add that when I tried to shut Jboss down with shutdown.sh
script it did not work. The script timed out.

I started setting TTL on the messages I publish to several topics. Now looking at the
