Per Steffensen commented on AMQ-1853: ------------------------------------- It is nice that there will finally be done something about this problem, eventhough I am not sure exactly that it is the same problem as I have been struggling with. This issue talks about the problem occuring if just on message is to be redelivered. The problem I have, only completely blocks delivery of new fresh messages, when there is more than maxMessagesPerSessions * maxSessions messages waiting for redelivery on the same consumer at the same time. I am using MDBs in Glassfish v2.1 as the consumer - maybe that makes the difference. For those with access - see more on https://fusesource.com/issues/browse/DEV-2279. Will this fix also solve my problem?

Looking at ActiveMQMessageConsumer.rollback(), I was thinking > something in the lines of just scheduling a task to put the message back on > queue after a delay - if configured to, instead of stopping delivery and a > schedule a task to resume delivery again.
