For the last 2-3 days I have had recurring issues with mongodb randomly cashing, the last crash the logs displayed a segfault with a backtrace. usually they just said:

Fri Dec 10 08:52:50 [conn449] Uncaught std::exception: std::bad_alloc, terminating

The site in question is in production so this is starting to look bad, I have attached the log of the last crash. If I could get some help fixing this issues that would be grate, if you need any more information let me know.

Thanks,
Matt
