>Description:
A series of reboots occurred to this machine. Sometimes the machine reset
automatically without kernel coredump left over, sometimes it just frose.
We had changed a new computer and had changed ipfw to ipfilter, but it
didn't work.
This is one of those coredumps which was saved after authomatic reboot.
It runs ipfw and natd as a firewall.
