well, after cvsup'ing and building of the world, the network seems to work a
litte better.
but under faily heavy load (flood pinging _form_ the host and floodpint _to_
the host) results in a trap 12. seem that actually the heavy output kills
the machine.
Fatal trap 12: page fault while in kernel mode
faul virtual address = 0x8
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc019d05c
stack pointer = 0x10:0xc8967ce4
frame pointer = 0x10:0xc8967d10
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 266 (ping)
interrupt mask =
kernel: type 12 trap, code=0
