Comment 6 for bug 71468

i testet too and got the following:

i have 2 feisty pcs and one has a pppoe intenret dialup connection.

I copied lots of files from the pc without internet to mine (with internet)
after some time and traffic the network broke down.

It was not possible that i ping the other pc and he couldn't ping mine. Restarting the other pc does not help

i tried on mine (wiht the internet and dnsmasq and ipmasq)
/etc/ini.d/dnsmasq restart
/etc/init.d/ipmasq restart
/etc/init.d/networking restart

the only thing that helps was restartin my maschine (the internet maschein)

It seems to be a traffic issue because if had it two times while copying large amounts of data.
Wioth normal traffic it works for about 2h that it crashes.

is also got lots of these
[ 232.870897] IN= OUT=eth0 SRC=192.168.1.101 DST=212.116.161.38 LEN=60 TOS=0x00 PREC=0x00 TTL=64 ID=39841 DF PROTO=UDP SPT=32770 DPT=53 LEN=40

but execpt them no strange errors in logs
