>Description:
The box runs rtorrent and after a few days of low-med traffic it becomes
unable to move traffic in or out. It is pingable, but cant move trafic,
so you cant SSH in, for instance.

The problem was there in 7.0b3 aswell. We didnt notice on 7.0b2.

>How-To-Repeat:
We can repeat by starting rtorrent on the machine and letting it run
traffic for a few days.
>Fix:
We have to coldstart the box to fix.

 It actually looks as if RC2 solved the problem.
 
 Thanks.
