Committed revision 1574119. On 64b architecture the issue can be verified, but on the 32b arch. the issue is still present:
1. qpid-receive -a "amq.direct/#; {link: {x-declare:{'auto-delete':False}}}" -m 1 -f
2. qpid-stat -q | egrep '(queue|=|direct)'
queue dur autoDel excl msg msgIn msgOut bytes bytesIn bytesOut cons bind

Topic subscription created by qpid-receive set auto-delete flag properly (amq.direct_bad38732-af89-480e-bf7a-ae953e53db27 queue was not auto-delete queue, so that is right). qpid-send as a message producer does not create any subscription or queue.

Disregard, got it. The reason why queue is deleted(*) is because the client deletes auxiliary queue for topic subscription, whenever the queue is exclusive. That's some feature I was not aware of but makes sense (to do some garbage collection and to prevent others to use mine exclusive auxiliary queue once I am gone). So, to let the queue persist, set exclusive flag to false, i.e.: qpid-receive -a "amq.direct/#; {link: {x-declare:{'auto-delete':False, 'exclusive':False}}}" -m 1 -f In either case (with or without exclusive:False), the queue is not auto-delete, what was the issue of this BZ. The exclusive:False just allows us to really see the queue any time later. (*) in my case, the queue is deleted on either architecture (i686 and x86_64). Reassigning back to QE to confirm my observation / autoDel flag setup. verified on qpid-cpp-0.30-2.el6.x86_64 qpid-cpp-0.30-2.el6.i686 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
