It isn't really possible for messages to get ``stuck'' in a queue.

If there are consumers on the queue, then the messages should get
delivered to them.

A few questions:
  * Are you sure the consumers are written correctly and that they're
    getting messages off the queue?
  * Are you in no-ack mode or are you explicitly acking the messages?
    Otherwise, the messages will get deliverd but will not get taken off
    the queue.

Hope this helps.

Cheers,
Alex
