I get this message quite frequently also...  but.. I don't understand
the following code fragment at all..  (yeah, I'm an idiot.. :-) )

Grok?  I don't have GATEWAY or LLC options in my kernel if that says

I thought this might be related to my having a "secondary ip address" on
the same physical segment.  (i.e. xx.xx.20.0 and xx.xx.24.0) But I still
get it with the box on a separate (single ip net) segment...

Maybe somebody could enlighten me?
