Fixed In Version: python-qpid-0.22-19
Doc Type: Bug Fix
Doc Text:
Previously, the neutron messaging client rewrote (by method of "monkey-patching") the python selector module to support eventlet threading. The rewritten client did not update select.poll() during this process, which is used by qpid-python to manage I/O. This resulted in poll() deadlocks and neutron server hangs. The fix introduces updates to the qpid-python library that avoid calling poll() if eventlet threading is detected. Instead, the eventlet-aware select() is called, which prevents deadlocks from occurring and corrects the originally reported issue.

Comment 3 Toni Freger 2015-01-18 08:48:40 EST 
Unable to verify due to missing of the python-qpid package within the RHOS5-RH7 repository : 
http://download.eng.bos.redhat.com/rel-eng/OpenStack/5.0-RHEL-6/latest/RH6-RHOS-5.0/source/
Comment 4 Eric Sammons 2015-02-11 11:38:46 EST 
This issue is not applicable to the earlier versions of RHEL OSP.  The fix was included in this release of MRG Messaging and sanity testing; regression testing here and el7 versions of this fix were in fact verified.
