 Replying to [comment:57 dcf]:
 > The patches from comment:54 have stopped the frequent crashes. Now the
 process is restarting according to schedule.
 > Here are the fd and memory graphs. Now we see memory slowly increasing
 over time--hard to say at this point whether it's just normal elevated
 usage or a leak. I'll leave the monitor running.

 Updates. Restarts are stable, memory and file descriptions seem fine.

 I'm thinking about losing the periodic restarts, and just putting a memory
 ulimit on the processes (just in case).
