Basically at BIG TCP-stream transfers (100 - 400 MB at
a time!) I got breaks at the transfers over ethernet.
(Runtime generated streams, and thus only 100-300 kB/s)
I had also gotten spodaric reports that FTP from ftp.funet.fi
over slow SLIP/PPP links has tendency to break after about
15 minutes time, and when I did network traces, I could not
find anything wrong...
However it didn't always (I recall) take 15 minutes to get
a break at the FTP data-stream, nor with my test-streams
either. As the last changes were about TCP timers, that
was the bug then. (..perhaps..)
Things are improving :-)
