Hello again, We did more testing on this issues. I think the problem is related to the pre-fetch parameter. If we force the prefetch to 1 on the connection factory, then using a AUTO_ACKNOWLEDGE and non-transacted session is working fine (but slow).
If we use the default pre-fetch (1000) then messages are not all removed from the queue. Thank you -- View this message in context: http://www.nabble.com/Message-is-read-but-not-removed.-t1649736.html#a4759864 Sent from the ActiveMQ - User forum at Nabble.com.
