What does '*reply.celery.pidbox' stand for

Question

We are using Celery with RabbitMQ as Broker and Redis as Backend. We are running into a problem where we see growth in the number of queues inside RabbitMQ with the format: 000d7a5b-f554-3817-bff4-1397407ae08a.reply.celery.pidbox

We are not able to understand why these queues are getting created, and why they are not going down.

Any help would be appreciated.

This Github issue gives some idea: https://github.com/celery/kombu/issues/294. I have seen the same issue on our Redis boxes. A comment on the issue recommends disabling gossip and mingle to overcome this.

Hope this is a bit helpful.
