That said, the SERVER project is for bugs and feature suggestions for the MongoDB server. As this ticket does not appear to be a bug, I will now close it. If you need further assistance troubleshooting, I encourage you to ask our community by posting on the MongoDB Community Forums or on Stack Overflow with the mongodb tag. |
