Hi, we have the same problem when upgrading to xena.

In our case, it seems that xena rabbitmq image erlang version is upgraded to 26 and rabbitmq version is 3.9.29 

According to rabbitmq documentation Maximum supported Erlang/OTP version is 25.2 for rabbitmq version 3.9.29 (https://www.rabbitmq.com/which-erlang.html)

rabbitmq-xena image id: 428f5f6c8fdd (created 30 hours ago)

It said that Erlan 26 is not officially supported for same problem: https://stackoverflow.com/questions/76274566/rabbitmq-closed-connection-on-method-createmodel

()[rabbitmq@7b64a8613ac1 /]$ erl --version
Erlang/OTP 26 [erts-14.0.1] [source] [64-bit] [smp:1:1] [ds:1:1:10] [async-threads:1] [jit:ns]

()[rabbitmq@7b64a8613ac1 /]$ rabbitmqctl --version
3.9.29

Probably same problem exist for yoga images too. See the bug : https://bugs.launchpad.net/kolla/+bug/2024888
