My compute nova.conf looks like following
[oslo_messaging_rabbit]
rabbit_retry_interval = 20
rabbit_retry_backoff = 3
rabbit_interval_max = 60
rabbit_transient_queues_ttl = 300
rabbit_qos_prefetch_count = 100
rpc_conn_pool_size = 300
Feel like something crashed in oslo driver and not able to recover itself. I have other deployment running on stein and i haven't seen this kind of issue in last 3 years so definitely this is something related to wallaby oslo bug.
