Just hit another last night. (Box goes to db> ; let me know if you want
to debug anything when that happens.)
I am sure there were no interface changes on the box and it was sitting
idle. (Unsure of the other subnets part.) And I am on 3 days old -head
so I already have r286945. I disabled IPv6 on the box just to eliminate
that but panic still happens.
