They're running out of memory because they have too much stuff running
on them that uses memory :) Rabbit is one of the processes
(apparently the hungriest single process), but it's far from the only
process. To be honest, I'm not sure why it's the hungriest process
either, but perhaps my other thread will help resolve that.

That's another problem, I guess. When rabbit starts, it truncates its
previous logs (at least by default). Our system has a supervisor
process that restarts dead processes, so when rabbit dies it gets
restarted immediately, which loses the logs of the previous crash. I
suppose I should put some log rotation in my rabbit startup code, but
I haven't done that yet. Is there an option to have rabbit rotate its
old logs, instead of truncating them?
