I think this can happen when the Airflow worker lost completely the access to the Metadata, where in this case it will not be able to update the task state, and if we use it as a result backend for Celery commands, then the Celery workers will not be able to send events to the DB which the scheduler processes to re-queue the failed tasks. I'm not sure if we check for workers heartbeats, where I didn't find this check in the method `_process_executor_events`, @potiuk can you please confirm this or send a link to the part which checks if the worker is still alive? -- This is an automated message from the Apache Git Service.
