How many consumers do you have on the queue, and how many messages have been dispatched (but not consumed) to each? And what prefetch size are they using? The default prefetch size is 1000; any chance you have three slow consumers that are each sitting on a full prefetch buffer?
Are you seeing the pending count on the web console, or somewhere else? And what version of ActiveMQ are you running? That's important information anytime you ask a question on this mailing list.
