no i do not.  bring server up and it'll happen in half an hour.

and the server was happy for two months.  so i am thinking hardware.

Perhaps. The reason I ask is that I had a box go down last night with the same set of errors. The box has a number of ipv6 routes, but its next hop was down and the problems started soon after. So I wonder if it has something to do with that. Do you have ipv6 on this box and are all the next hop addresses correct / reachable ?

Just a shot in the dark, as I got another private report just now
on this one; is any of you by chance running VLANs on the systems
you see this happening?
