> I experience the same problem. In the workers logs from last night I can see few dozen errors caused by deadlock. In the scheduler log I can see only one deadlock error, after which scheduler was restarted. Here is a gist containing the logs: https://gist.github.com/tulanowski/fcc8358bad3c8e5d15678639ec015d8b > > Airflow version 2.2.0 MySQL 5.7.33 running on AWS RDS Celery executor with 6 workers 1 scheduler replica > > Hope it helps! If I am not mistaken, it did :). The (very likely IMHO) fix is in #21362. Question @tulanowski - > would it be possible that you patch your Airflow instance with the fix (it's really simple) and see if it helps? It just passed all the tests in the latest fixup, so it should be safe to copy. Also - just to confirm - do you happen to have some tasks that throw AirflowRescheduleException occasionally ? Because IMHO this is when it could happen when you are unlucky and race condition happens. -- This is an automated message from the Apache Git Service.
