Comment 5 for bug 1954925

I also wonder if enable_cancel_on_failover oslo_messaging setting is related, to when ha failover happens, stop clients retrying all the time, which might be related to why rabbit is so busy logging these errors, but its a total guess:
https://github.com/openstack/oslo.messaging/commit/196fa877a90d7eb0f82ec9e1c194eef3f98fc0b1

I have seen issues with neutron agents, when rabbit fails as described above, eventually they go inactive. It feels a bit related.
