Celery Worker Stops Consuming Tasks After Redis Restart
  • When Redis is restarted, Celery workers using Redis as a broker may stop consuming tasks without exiting or logging a fatal error.
  • Although Celery Beat continues to publish tasks successfully, the worker remains in a broken state until manually restarted.
  • This results in a silent backlog of scheduled but unprocessed tasks.
