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. <br>

I have a moderate-traffic queue on rabbit 1.8.1 that for some reason doesn't ever get smaller than 1.3k (as reported by rabbitmqctl list_queues). �<a href="http://i.imgur.com/m6Zva.png" target="_blank">http://i.imgur.com/m6Zva.png</a><br>

The queue has two consumers that have been killed/restarted (several times), so it's not a matter of them being stuck in a consumer. It's not an issue of not being able to process them fast enough, because if I shut off the consumers to let the queue grow a bit then turn them back on, messages are processed down to that point near-instantly (that's the giant spike in the aforelinked graph).<br>
<br>
Any idea why these messages can't be retrieved?<br>
