I have had these problems since a long time during 1.3.X and now also on the 2.0.X Kernels. Somewhere in between it got worse and then better (1.3.8x) but now I got the stalls frequently again.
I am still experiencing problems with Linux Networking. Telnet sessions from the same host are stalling others are still moving along. Can anyone shed any light on why there is a huge send-queue for one telnet session and not for the other?
Setup: Dialin from Linux System at home (2.0.8) into Modem Server (2.0.8). Telnet session is from the home system to another host on the network which runs a full Usenet feed. Two systems are running Debian 1.1 one Slackware 3.0. In both of these cases the stalling session was running tin to read news. I have removed diald for these tests. Just ppp-2.2.0f is involved.
