Kevin Earls commented on AMQ-4920:
----------------------------------
Sorry, it's still failing for me. I'll attach a log where I ran the test 50
times and got 16 failures. After each failure I grepped for error messages,
most of which look like:
2013-12-17 09:50:36,657 [pool-1-thread-4] - ERROR AMQ4930ConsumerTask
- consumer Consumer-3 expected 291 got message [topic]
or
2013-12-17 09:49:32,429 [pool-1-thread-3] - ERROR AMQ4930ConsumerTask
- consumer Consumer-2 expected 646 got message
