I am using Windows Azure Service Bus. I created a Topic and am using a subscription to which partners send messages to. What I notice is that the "Message Count" stays at 1923 and does not come down. When a new message is posted to the queue (or subs in this case), it goes up to 1924 and then my service polls the message and it will bring it back to 1923. It looks like 1923 messages appear to be stuck and unable to retrieve.
Why does this happen and how do I retrieve these messages?
