We receive emails when a user encounters an error. When it is a mongo error, we expect to be able to open the log file and find the command the user was attempting when the error occurred. For example:

MongoDB.Driver.MongoCommandException: Command find failed: errmsg: "Sort operation used more than the maximum 268435456 bytes of RAM. Add an index, or specify a smaller limit.".

These errors are not always in the mongo log file
