commit: ee955d272ab4eef2e8371f2e460454058ce7e46c
This happens sometimes when I restart nova-conductor and nova-compute services.
Is this the same cause of bug https://bugs.launchpad.net/nova/+bug/785816?
The trace is here:

This happens sometimes when I restart nova-conductor and nova-compute services. The notification via rabbitmq is enabled in nova.
Is this the same cause of bug https://bugs.launchpad.net/nova/+bug/785816?
