That totals 4 packets that are ill-formed in a period of 2 hours, 
packets which are causing the router to crash. That's a bug, period.

This has nothing to do with what happened this morning - those were 
incorrect source addresses.

A router that doesn't drop an ill-formed address in an ARP packet has a 
bug. A router that crashes due to this has a fatal bug.

Let's replace that router, and debug THAT offline.

If you had bothered to ask, it isn't even my stuff. It's Lars'. I'm 
running (still, since this morning, and haven't stopped)- WinXP (gasp).
