Comment 4 for bug 2051365

> Perhaps the problem is related to having a CMR between a k8s and a machine model, as I see the problem when I have a CMR with both juju 3.1 controllers and a k8s model, but don't see the problem when I have a CMR with both machine models.

I've added juju to the bug; it does sound like an issue with Juju rather than the rabbitmq-server charm; I'm setting the rabbitmq-server charm to invalid; however, if it does turn out to be a charm bug, please do re-open the bug.
