Comment 8 for bug 1701327

I am still debugging, for now I don't have any findings on these issue.
I have issued port-update continuously and didn't observe this error on ocata setup.

@Sridhar will it be possible to reproduce the issue again? If yes, can you please provide the output of 'rabbitmqctl list_queues' at the time of error and also the neutron server and agent logs.
