I wonder if either of you could try out trunk to see if the problem is still there? There's been a number of patches in the acknowledgement code of late. (Unfortunatley the nightly snapshots haven't been working for a little while but we'll hopefully get them working again ASAP).

Hi, I've noticed the same behavior. Every now and then a message will be visible through the JMX interface but not accessible to consumers. I'm using ActiveMQ 4.1.0 for both the broker and clients. We have a single producer and about 1000 consumers. The consumers use queuePrefetch=1 and AUTO_ACKNOWLEDGE sessions.
