[rabbitmq-discuss] pile up messages on queue

Perhaps auto-ack is false, and you are not ack'ing the messages?  You can check the number of unack'd messages in the management console.

It's not clear to me what you are trying to do and what the issue here.
Specifically, I'm not sure what you mean by "getting" from the queue and "cleaning" the queue.

If you are consuming from the queue, logically the messages should not appear again on the queue (unless you are rejecting them). Are you experiencing redelivery of messages that you have consumed already?
