 Description   

mongod segfaulted apparently for no reason (unable to correlate this with anything remarkable in the application logs).

For some reason it was building indexes just before the crash. Not sure why it was doing that (nothing in the application's log suggested an action that would have triggered this).

As you can see from the logs, there are some truly nasty queries, a lot of suboptimal stuff going on. I've got some big improvements in the pipeline but they're not deployed yet.

As a result of this crash I've upgraded to mongod 2.0.1 and am now setting up MMS.

For what it's worth this DB has run flawlessly for at least three months now.
