Hi Simon. Thanks for the update.

Where you also able to observe the other issues that occur in this state? 
Such as:
* rabbitmqctl cluster_status/list_queues/list_connections/list_exchanges all 
hang, rabbitmq status does not hang
* declareQueue, declarePassiveQueue, declareExchange, declareExchangePassive 
all hang


One last thing I wanted to add to this. When I run this on average hardware 
(4 core 2GHZ, x86, 8GB ram) the issue is still seen, but not as noticeable. 
When I run this on much more modest hardware (PPC 2core 1GHZ 1GB RAM) The 
issue is several of orders of magnitude worse, but otherwise this lower end 
hardware is sufficient for the message load.

Thanks,
James
