[rabbitmq-discuss] Queue has inaccessible messages?

Sat Oct 2 12:42:40 BST 2010

Are you sure the connection on the broker is being closed after you kill
your consumers? I have a similar problem and sometimes have to manually
close the connection on the broker in order to get messages delivered to the
consumer.

See this thread for details
