> When publishing a task with qpid.messaging it deadlocks and our application
> cannot continue. This has not been a problem for several releases, but within
> a few days recently, another Satellite developer and I both experienced the
> issue on separate machines, different distros. He is using a MRG built
> pacakge (not sure of version). I am using python-qpid-0.32-13.fc23.
> Both deadlocked machines had core dumps taken on the deadlocked processes and
> only show only 1 Qpid thread when I expect there to be 2. There are other
> mongo threads, but those are idle as expected and not related. The traces
> show our application calling into qpid.messaging to publish a message to the
> message bus.
> This problem happens intermittently, and in cases where message publish is
> successful I've verified by core dump that there are the expected 2 threads
> for Qpid.
