Odd network trace...

Hi,

In the following trace, near the end, I see the server ack-ing all
data sent sofar, but the client (Linux version 2.2.17 (root@cave) (gcc
version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #4 Fri Oct
27 14:54:42 MEST 2000) does not continue to send further data,
although that IS available (the transfer should end at about 6Mb).

Am I missing something?
