I'm using clustered JBoss 4.2.2 on two Linux boxes.

I have a stand-alone client that uses the HA-JNDI to post messages to 10 different queues. They are retrieved round-robin style by each of the two nodes.

After running for a little while, I get this error:

WARN [BasicQueue] Caught unusual exception sending message to receiver.
