Hi, All
Recently I came across many AssertionError messages in nova log as follows
Exception AssertionError: AssertionError() in<module 'threading' from
'/usr/lib/python2.7/threading.pyc'> ignored
After some investigation, it turned out to be introduced by eventlet
0.9.16-1ubuntu4 which is the default version in Ubuntu 12.04 LTS.
Based on the information from Ubuntu package changelog (
https://launchpad.net/ubuntu/+source/python-eventlet/+changelog ), it
seems to be some portion of Johannes's eventlet memory leak fixing
patch was backported to this version. While other monkey patch change
was left out, applying following patches could fix the issue.
Although this message may not relates to OpenStack itself, thought
someone in this list may take interest. Just FYI. Thanks.
FYI, I've opened a bug for this against python-eventlet in Ubuntu. The
fix will hopefully be accepted to precise-proposed soon, and be ready
for verification. If someone who is interested in seeing this fixed can
subscribe to the bug, and provide verification of the fix once it lands
in -proposed, we can ensure the update hits 12.04 quick. Thanks!
