Fixed In Version:	python-qpid-0.18-12	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.	Story Points:	---

Comment 4 Petr Matousek 2014-06-16 17:26:45 UTC

This issue is fixed with python-qpid-0.18-12.el6

# neutron net-list --format=csv --column=id --quote=none
id
508fabf2-ce48-4258-b674-5346d4d6afb0
328de1c7-7569-4b87-8ea8-9ba2979ee76a

Packstack installation was successful without any issues.

Note: skipping test for python-qpid.el5 due to lack of rhel-osp5 support on rhel5.

-> VERIFIED
