Changes in oslo.messaging for 2023.1 exposed a known race condition in RabbitMQ when dealing with non-HA classic queues. When a RMQ cluster member is taken down, clients failing over to other members may erroneously be told a queue exists when it is in the process of being deleted. This can cause them to permanently sit waiting for messages from a queue that no longer exists until their services are restarted. Making the reply queues HA resolves this issue, at the expense of a x3 increase in reply queues across the cluster. My assumption is that reply queues were previously excluded from HA policy as a performance gain given their link to the number of compute nodes in an OpenStack deployment.
