I have commented out the lines with the /* else it is lost forever */ in
arp.c and turned off the DEBUG stuff in route.h. ( This is all in 2.0.30 )
The problem seems to have gone away, but.... Now I get:

This has happened a couple of times now. It basically loses the NIC where
the aliases are. ( only one NIC has aliases on it )

Any thoughts?
