So the 10 connections in your test simulate the connections from the f/e 
server, and the 20k queues per connections is the number of clients 
connected to that server? If so, surely having the queues exclusively 
owned would prevent clients from moving between f/e servers. You may 
want to look at the "queue leases" feature 
(http://www.rabbitmq.com/extensions.html#queue-leases).
