c.aaron.clements, the SERVER project is for reporting bugs or feature suggestions for the MongoDB server. For MongoDB-related support discussion please post on the mongodb-user group or Stack Overflow with the mongodb tag, where your question will reach a larger audience. A question like this involving more discussion would be best posted on the mongodb-user group.

I'd also suggest you check out this post from Adam C explaining the error messages you see in more detail and how to proceed.

Regards,
Ramón.
