I am running Mongo 2.2.1 in ec2, I have enabled profiling and I'm sending a slow op summary every 180 sec to graphite. Every now and again the script reports an error (BSONElement: bad type 113) and if I log to the Mongo shell and run a db.system.profile.find() I get a more detailed report:

I am fairly new to MongoDB, any help appreciated.
