I was wrong. You have more than 47,000 connections! And the same number 
of channels (unsurprisingly). But you "only" have about 16,000 queues.

Congratulations. This is by far the fattest rabbit I've ever seen 
(except those stuffed full of messages).

I have no idea why all these connections, channels and queues are there. 
That's a question for the celery guys.
