I've been running my instances for over 5 years, I update the Dockers every few months and that's it. I have about five users in different households that rely on it it has never missed a beat.

I’ve had mine going for what feels like ten years now no issues. Even longer if you could some of the earlier managers out there. The arrs are some of the most solid apps I’ve run. Especially once I switched them to use Postgres.
