Does this sound like a likely cause?  I've identified and removed the code that was creating all the channels, but I'm concerned that it appears to be so easy for a single rogue client to take down the entire server.  Is there a way for me to prevent this?

Having said all that however, be aware that you'll also crash if you run
out of file descriptors, and you can also explode rabbit by creating
lots of queues - there are no limits on either of these. So there are,
sadly, several vectors for DoS attacks just at the moment.

/me raises further bugs.
