What kernel are you running? This is disabled by default. search for
where FASTRETRANS_DEBUG is enabled (should be in linux/include/net/tcp.h
and set it someting low (like 1 which is the default. The actual error
message comes up in tcp_input.c (search fro FASTRETRANS_DEBUG).

Regards,
Bart.

That is 2.4.4-pre3

Thanks, Bart. Looks like it was set to 2. I have set it to 1 and will build
it again. I am trying to figure out why 2.4.4 (or to be more accurate
2.4.>1) dies on me when running in my web farm. This last time I tried
running top in the background with:

top -b -i -d10 >crap &

And it has run like a champ! First time I have ever been able to run it
with good performance for more than 15 minutes. Maybe I will just
substitute /dev/null for crap and that will fix it :-/
