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. > changeset: 1863:6603e234fc56 > user: Johannes Erdfelt <johan...@erdfelt.com> > date: Fri Mar 02 18:09:41 2012 +0000 > summary: Make sure _after_fork gets patched too so forks don't print > spurious > changeset: 1865:f3fd4562f347 > user: Johannes Erdfelt <johan...@erdfelt.com> > date: Sun Mar 18 14:38:27 2012 -0700 > summary: Ensure threading._shutdown gets patched too Best Regards, -- unicell _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
