   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:

   Airflow version 2.2.0
   MySQL 5.7.33 running on AWS RDS
   Celery executor with 6 workers
   1 scheduler replica
   
   Hope it helps!
