Subject Re: Large difference for (dequeue + inflight) and dispath counter for queue.
Date Thu, 04 Jun 2015 18:37:39 GMT
If a consumer disconnects while there are messages in its prefetch buffer
and then reconnects, the messages in the prefetch buffer will be dispatched
again without any enqueues or dequeues.  How much it goes up by each time
depends on how many messages are in the prefetch buffer at the time.   That
may not be the only possible explanation (and there could always be a bug),
but it's one.
