Re: [Openstack-operators] [oslo] RabbitMQ queue TTL issues moving to Liberty

The queue TTL happens on reply queues and fanout queues. I don’t think it should happen on fanout queues. They should auto delete. I can understand the reason for having them on reply queues though so maybe that would be a way to forward? Or am I missing something and it is needed on fanout

I have filed a bug in oslo.messaging to track the issue [1] and my colleague Kirill Bespalov posted a fix for it [2]. We have checked the fix and it is working for neutron-server, l3-agent and dhcp-agent. It does not work for openvswitch-agent and metadata-agent meaning they do not stop RPC

Re: [Openstack-operators] [oslo] RabbitMQ queue TTL issues moving to Liberty

Sam, For your case I would suggest to lower rabbit_transient_queues_ttl until you are comfortable with volume of messages which comes during that time. Setting the parameter to 1 will essentially replicate bahaviour of auto_delete queues. But I would suggest not to set it that low, as otherwise
