Fixed In Version:	openstack-heat-2013.2-4.el6ost	Doc Type:	Bug Fix
Doc Text:	When the QPID broker is restarted, RPC servers attempt to re-connect. However, a bug in the QPID topic consumer re-connection logic (under the v2 topology) caused qpidd to use a malformed subscriber address after restarting. This caused qpidd to incorrectly establish multiple subscriptions on the same fanout address after reconnecting. The QPID broker only requires one subscription; each extra subscription created duplicate RPC notification samples for individual services (e.g. Heat). This release removes the special-case reconnect logic that handles UUID addresses, which in turn avoids the incorrect establishment of multiple subscription to the same fanout address. The QPID broker will simply generate unique queue names automatically when clients reconnect.	Story Points:	---

Since this issue was entered in bugzilla, the release flag has been
set to ? to ensure that it is properly evaluated for this release.

Checking into risk of fix; may want to take for 4.0GA

--- Additional comment from Perry Myers on 2013-12-05 11:29:29 EST ---

This seems important enough to be an RC blocker for 4.0.  But doesn't this bug need to be cloned to Nova, Ceilometer, Neutron, etc (every component that copies and pastes the code from Oslo for RPC?)

Restarted qpidd and verified Heat stack operations create, delete, and list worked properly. (Patch info in comment 1.)
