Hi,
	I am seeing this issue as well on a pair of  recently deployed
boxes, one  running MPD and one acting as an area router in front of
it. The MPD box has a default route and only has 400 routes or so.

A steady stream of those messages, upwards of 500 per second.=20

got message of size 96 on Fri Jun 27 22:25:42 2008
RTM_MISS: Lookup failed on this address: len 96, pid: 0, seq 0, errno
0, flags:<DONE>
locks:  inits:=20
sockaddrs: <DST>
 default

Is there a way to try and track down what is generating those messages
? Its eating up a fair bit of cpu with quagga (the zebra process
specifically)
