RTM_MISS is actually fairly common when you don't have a default route. Messages which get enqueued don't necessarily get delivered -- and very few processes actually listen to the routing socket actively like this, so I wouldn't worry about it. If it's a real concern for you then you could try hacking in a sysctl to tell the radix trie code not to issue RTM_MISS messages on the routing socket.
