I have a Linux Firewall, me being Paranoid about it, I have a process watching all traffic and ethernet conditions.
Evidentally, the process saw something unexpected. Went into PANIC mode, dropped everything In or Out.
What actually happened, one of two power supplies died. It let the magic smoke out of itself. Darn it... tough to get the stuff back in. Currently running on one power-supply. When I took the bad one out, noticed the contacts to the bus-bar were burned to a crisp to. Might be getting a replacement under-warranty (power-supply and bus-bar set.
Looking at logs, it appears the burn-out caused spurious packets. Hence the Paranoid response.
Sorry for the outage. Burnout happened at 6AM EDT. Might have been screwing the packets up before that.
