Hi all.
I found that RabbitMQ was actually broken after the upgrade (feature flag loop, then schema errors), without any obvious issues at first. (checked it via journalctl -b | grep -i failed). I saw many restart trys.... (every 10s).
In the end RabbitMQ refused to start because of a missing internal table (schema_integrity_check_failed).
I fixed it by stopping RabbitMQ and deleting /var/lib/rabbitmq/mnesia/*, then starting it again.
After that RabbitMQ started cleanly and everything works fine — is this the intended fix, or did someone find a better way?
Regards.
