Local MongoDB Errors

Hey All!

I am hoping someone can help me out here. I am running the latest version of Meteor for several apps, and it seems that randomly I get the following Mongo error:

Unexpected mongo exit code null. Restarting.

I know that I can just delete the local DB folder and the problem is solved; however, some of my local apps require quite a bit of mongo to run, and the process of re-importing data from my web-server mongo instance is a huge time suck.

Is there any reason this is happening? Is there a fix that does not involve blowing out all of my local data every time? Possible meteor bug?
