Public bug reported: python-eventlet (0.9.16-1ubuntu2) introduced a cherry-picked upstream patch that fixed a memory leak manifested by Nova's use of the library. Since that time, the various nova services often log AssertionError exceptions, ie:
2012-07-01 17:59:27 DEBUG nova.utils [-] Got file lock "iptables" for method "apply"... from (pid=23798) inner /usr/lib/python2.7/dist-packages/nova/utils.py:942 2012-07-01 17:59:27 DEBUG nova.utils [-] Running cmd (subprocess): sudo nova-rootwrap iptables-save -t filter from (pid=23798) execute /usr/lib/python2.7/dist-packages/nova/utils.py:219 Exception AssertionError: AssertionError() in <module 'threading' from '/usr/lib/python2.7/threading.pyc'> ignored 2012-07-01 17:59:27 DEBUG nova.utils [-] Running cmd (subprocess): sudo nova-rootwrap iptables-restore from (pid=23798) execute /usr/lib/python2.7/dist-packages/nova/utils.py:219 Exception AssertionError: AssertionError() in <module 'threading' from '/usr/lib/python2.7/threading.pyc'> ignored 2012-07-01 17:59:27 DEBUG nova.utils [-] Running cmd (subprocess): sudo nova-rootwrap iptables-save -t nat from (pid=23798) execute /usr/lib/python2.7/dist-packages/nova/utils.py:219 Exception AssertionError: AssertionError() in <module 'threading' from '/usr/lib/python2.7/threading.pyc'> ignored 2012-07-01 17:59:28 DEBUG nova.utils [-] Running cmd (subprocess): sudo nova-rootwrap iptables-restore from (pid=23798) execute /usr/lib/python2.7/dist-packages/nova/utils.py:219 Exception AssertionError: AssertionError() in <module 'threading' from '/usr/lib/python2.7/threading.pyc'> ignored 2012-07-01 17:59:28 DEBUG nova.network.linux_net [-] IPTablesManager.apply completed with success from (pid=23798) apply /usr/lib/python2.7/dist-packages/nova/network/linux_net.py:335 As was pointed out on a recent mailing list post [1], this is due to two missing patches that were subsequently applied upstream to avoid the exceptions. The issue has been fixed in Debian unstable as of 0.9.16-2 (a more complete patch applied), and in Ubuntu as of the 0.9.16-2ubuntu1 merge. We should consider SRU'ing a fix for this as it is unsettling for users deploying Nova into production, and annoying for upstream developers (12.04 is the current target platform for the current Nova dev cycle).
