Could it be tied to some event from underlying network? Maybe run tcpdump on both broker 
and client to make sure all packets reach their destination in each direction. Tcpdump 
should also show if messages published after hang occurs are being delivered to your 
consumer or not.

Also, you might be able to isolate the issue by running your consumer code on broker 
machine - this will eliminate the network from the equation.
