kernel: arpresolve: can't allocate llinfo for 65.59.233.102

[Dominic Blais]

Hi,

I just made a script that does the following:

5 times
do
   if default_route != PROPER_GATEWAY
	delete_default_route()
	create_default_route_with_proper_gateway()
   fi
   sleep 10 seconds
done

It worked well and replaced the default route within 10 seconds (mean 5).

What's interesting is that route monitor shows that I delete and create the default route but doesn't show anything prior to it. So I think it really confirms it's some kind of a bug somewhere that takes an IP address that's in memory in put it as the default gateway.

Hmm, interesting. We need more debugging here. But where from could 65.59.233.102 appear?
