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.
