Hi

One thing i should have mentioned is that this only happens with 
rtorrent. For example i can transfer in 10Mbit+(not much plus) from 
work, where i have no bandwidth restriction, for hours without problems. 
Using scp, i have not tried with ftp and very large files. When i 
transfer large files from work with scp i can maintain a speed of 
10Mbit+ for long periods of times without problems. This problem has 
only happened because of rtorrent using a lot of bandwidth. And as i 
said earlier it happens when using less bandwidth to.
