> Root Cause This addresses a known upstream Celery bug (https://github.com/celery/celery/issues/8030, https://github.com/celery/celery/issues/9054, https://github.com/celery/celery/issues/8990) where after a Redis broker restart, the worker reconnects at the transport level but fails to re-register its consumer on the queue. The worker process stays alive, celery inspect ping returns OK, but inspect.active_queues() returns None. Tasks pile up in the Redis queue and are never consumed. > The partial fix in https://github.com/celery/celery/pull/8796 did not fully resolve the issue, and it persists across Celery 5.2.x through 5.5.x with Redis broker. All reference issues are close ones. Do we have any open issue or a confirmation from Celery that this is an **open bug**? -- This is an automated message from the Apache Git Service.
