> Our Airflow setup uses Celery Executors and Redis as a broker. We are facing a issue of missing heartbeat from celery workers. Once this heartbeat is missed the worker stops taking any new task. It also appears as offline in the Celery flower UI. Manual restart of workers fixes this problem.
> Wanted to know if this is a known issue or being faced by other users in the community
> These are the logs from failure.
