Can you provide more information about the configuration of mpd and ppp?
the panic is in the dummynet code; can you provide information about
your ipfw/dummynet setup?
Thanks,

Hi all,
I'm doing tests with mpdas pppoeserver. Tried to simulate an attack of 1000
connections using an incorrect login and after a certain time can cause a
kernel panic in the system. Below the panicgenerated:
http://pastebin.com/nUXGVR3y
Other equipment I do:
# for (( i=0; i < 1000; i++ )); do ppp -ddial intnet ; done
My System:
Intel Motherboard Server S5500BC with Dual Processor Xeon(R) CPU E5606 @
2.13GHz
8Gb ram
I do not understand programming in Cor Assembly. But could someone tell me
if what happened was a system problem or hardware?
Best regards,
Gondim
