Comment 17 for bug 1586840

And here is stack trace to help in dealing with errors:

NOTE that I am running amqp 2.0 and Kombu 4.0.2 with oslo_messaging.
This seems to be a small issue in oslo_messaging not dealing with this type of error.
It's the only issue I've encountered so far after running this for some time.
