Comment 3 for bug 1229475

Mark, I an not sure what the actual bug is here. The first stacktrace was from rpc, but the second is from neutronclient.

Here is a third case of it: http://logs.openstack.org/87/44787/13/check/gate-tempest-devstack-vm-neutron/11d697f/logs/screen-n-cpu.txt.gz

Also until we get elastic-recheck fully running this one is hard to find for the untrained eye. But logstash shows its been hit 12 times in the last 24 hours.
