Hello, has somebody met stalled persistent emails in ActiveMQ 5.3.2? Something like AMQ-2009? As that should be fixed in ActiveMQ 5.3 while we see that in 5.3.2. In our case, ActiveMQ receives emails from James server, puts them into a queue where there are 50 consumers all with prefetch set to 1. To resolve the problem of stalled emails, it was enough to delete the very first (oldest) email stored in the queue and restart ActiveMQ. So it seems some particular email in some particular situation stucks ActiveMQ.
During the crazy time I was able to gather Java thread dump http://old.nabble.com/file/p29008536/thread_dump.txt.gz thread_dump.txt.gz where I see one peculiar thing: thread "ActiveMQ Transport: tcp:///127.0.0.1:59468" locks 0x0000002aa1c3c770 while other 15 threads are waiting for the lock. My questions are: 1) Have you experienced similar problems? What was the cause and resolution? 2) Is the thread dump ok? Esp. the locks? s for me it is strange that one transport thread (I suppose towards the consumers) blocks 15 others.. Thanks in advance for any help. -- View this message in context: http://old.nabble.com/ActiveMQ-5.3.2-stalled-emails-in-queue-tp29008536p29008536.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
