Comment 8 for bug 1910958

Ran into this bug in an environment yesterday.

The symptoms were "ERROR permission denied" during relation-get or relation-set requests.

However the tell-tale log of this error only appeared after jujud was restarted and had not appeared before then (or any other obvious error about the issue at the jujud level):
2021-05-31 07:20:55 ERROR juju.worker.dependency engine.go:671 "uniter" manifold worker returned unexpected error: failed to initialize uniter for "unit-rabbitmq-server-0": cannot create relation state tracker: cannot remove persisted state, relation 233 has members

Advising to assist others in diagnosing the issue
