Comment 16 for bug 1101404

I have hit the same issue on my system here. The test environment is CentOS 6.5, Python 2.6.6, Icehouse RPMs from RDO, eventlet 0.14. Our Nova services are configured with verbose and debug logging enabled. We also configured to log through syslog. Whenever syslog is restarted, if a log event occurs while syslog is down then nova-api spins exactly as described, OpenStack processing stops and the services cannot be gracefully shut down.

I tried the latest eventlet development snapshot, unfortunately it does not fix it. The proposed patch (linked to above) does work on our configuration.

I haven't tried upgrading to Python 2.7.6 - too disruptive - which has also been reported to fix the issue.
