Hello 

I am using ActiveMQ4.1.1 and running the Master/Slave Setup and to test it i
run the receivers in my clustered environment and the producer on my local
machine when i bring the Master down my producer sometimes hangs.  I also
have a TransportListener that is not getting notified. 


Here is the Thread dump
