I got more panic with DEBUG=-g and INVARIANTS. I saved core dump at
this time.
This panic is caused when I tested heavy traffic via aue0 (USB
ethernet adaptor) with "while looped" large file scp. I think that is
only active process.
My ipfw is set as default like as "65535 allow ip from any to any".
Should I give some data to solve this problem?
