Hi,
I was also working with the pipes and the machine crashed also....
But I saw something on console maybe it can help:
Fatal trap 12 : page fault while in kernel mode
fault virtual adress : 0x16c
fault code = supervisor read, page not present
instruction pointer: 0x8=0xc0183f46
stack pointer : 0x10:0xc677fea8
frame pointer : 0x10:0xc677fedc
code seeegment = base 0x0,limit 0xffff, type 0x1b
= depl 0, pres 1, def 32, gram 1
processor eflags = interrupt enabled, resume, iopl=0
current process = 1727 (perl)
interrupt mask =
trap number = 12
panic : page fult
Sorry if I made maybe 1 or 2 type errors but i had to write it down and then
type it in.....
The problem can be in two things either perl is buggy since that appears in
the error or maybe something in ipfw/dummynet since i was playing with them.
I cvsupped it thursday evening and build on friday.
