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.

Packstack installation was successful without any issues.

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