When upgrading a cluster from RabbitMQ 3.8 (via Ubuntu 20.04 LTS) to RabbitMQ 3.9 (via Ubuntu 22.04 LTS) there is a critical bug, causing new connections on the node running 3.9 to crash:

This was fixed in version 3.9.21 of RabbitMQ, thus is version is definitely required on Ubuntu 22.04 to allow for a rolling upgrade of clusters!
