I don't know. I guess we can see, but my guess is that it will wake me up at two in the morning to fix the site. That's what usually happens when rabbit crashes, anyway.

> The default Erlang gc performs garbage collections after a certain number of reductions, and that number is so high that a queue process which does work infrequently may not perform a gc for a very long time indeed. That's particularly noticeable when the message sizes are large. What's the average and max message size in your set up?

They're just IDs, so they'll be between 5 and 10 bytes each.

Yes

That doesn't appear to be true, no

No
