Subject Re: JDBC 300K messages stuck in queue, consumers receives messages when manually browsed the queue
Date Mon, 30 Nov 2015 16:36:05 GMT
One more observation:
Number of consumers being displayed on Admin UI are way more than actual
consumers.
Admin UI is showing incorrect? counts:
Pending Messages: 568073
Number of consumers 408 (I'm expecting only 69 consumers),
Messages Enqueued 354845
Messages Dequeued 45383

Thanks
Pankaj
