I've no idea why adding ACCEPT_MODE_NONE should cause it to misbehave, it should have simply removed the need to acknowledge should it not...
Sorry... one more complication with that combination... you will need to periodically call Session::sendCompletion(), certainly not less then every 100 messages. This is because if accepts are not required the auto-ack functionality is disabled and that is where the sendCompletion() is done autonatically. (Again, this is what you are avoiding by using the messaging API everyone! :-)
However, from the perspective of delivery records, if you set ACCEPT_MODE_NONE, you can leave the flow control as unlimited and you should still not build up any server side memory.
