"LockNotOwnedError: Cannot extend a lock that's no longer owned" When laptop goes to sleep. about redbeat

I run into the same problems as you, I do the same on my server. But when they work correctly for a while, the problem randomly arises. Nothing happens to the analysis log, as if the lock really expired and disappeared, but shouldn't it be renewed all the time?
So I was wondering if you found the problem?

I couldn't find a solution, but I increased celery_beat_max_loop_interval=30 in addition to redbeat_lock_timeout: int = celery_beat_max_loop_interval * 5. I've also made the containers restart on failure with docker compose. On kubernetes, the same.

It means that you solved the problem by shortening the polling interval of the beat service, ok，which is the only solution I have found so far
