I've been using 2.0.31-pre10 but recently I decided to try 2.1.57.
It's been running fine but yesterday I got this warnings in my syslog:

Oct 15 01:58:04 nuno kernel: TSW: win < 0 w=0 1=869542 2=869541

... It continues until ...

Oct 15 02:24:22 nuno kernel: TSW: win < 0 w=0 1=2450628 2=2450627

Oct 15 02:43:04 nuno kernel: TSW: win < 0 w=0 1=3572940 2=3572939
Oct 15 02:43:05 nuno kernel: TSW: win < 0 w=0 1=3572941 2=3572940
Oct 15 02:43:05 nuno kernel: TSW: win < 0 w=0 1=3572942 2=3572941

I see it's being printed in tcp_output.c but I would like to know what it
means. The machine continued to work fine and at the time I was just browsing
with Netscape and maybe receiving some mail.
If it's some kind of bug I can send more configuration details.
