I'm seeing this as well. It's very easy to reproduce:

1. Start listening for routing messages on a non-default FIB, e.g.
setfib 2 route monitor
2. Add any static route within that FIB.
3. The machine I run the test on is a heavy DNS client, it generates a
few dozen requests per second. The monitor process starts getting
RTM_MISS messages for each outgoing DNS request (the dst sockaddr is
the same as my first resolv.conf entry, seq is always 0).

Good, fast & cheap. Pick any two.
