Looks kinda like what happened was the server started, and a player tried to connect whilst it was still coming online.

You might try rebooting the physical machine. One other thing I just thought of, is this RW server running on a Virtual Machine?

This indicates that the server received an UDP packet, but couldn't find a connection for it... Maybe you could use a program like Wireshark to find out the IP of the sender.
