in.routed implements ICMP router discovery. Something on your LAN is sending
router advertisements that it doesn't like.
If your machine has manually set its default router, you can and should disable
routed:
routeadm -ud ipv4-routing
If your machine depends on in.routed running for either RIPv2 or for ICMP
Router Discovery, you should investigate the source of those messages.
