> Tested with a QueueSession.commit() method call.
> Taking a look at client thread dump, it seems there is a deadlock on FailoverValve2. The ConnectionValidator thread is waiting the messaging client thread leaving FailoverValve2, but it won't happen because the client thread is entering the FailoverValve2 and reading dead tcp socket.
> To reproduce this problem:
> 1. Apply the following patch to JBossMessaging_1_4_0_SP3_CP02:

> 2. Call QueueSession.commit() method on the client side
> 3. Disconnect the network cable from the server machine
> Or use a firewall. For example, iptables on the server side:
> iptables -A INPUT -s CLIENT_IPADDRESS/32 -j DROP
> iptables -A OUTPUT -d CLIENT_IPADDRESS/32 -j DROP
