netstat -w is loosing both input and output packets

[Boris Samorodov]

Hello All,


there seems to be a problem with netstat which I discovered while
testing a new ale(4) driver. Here is an example of "netstat -w 1":
netstat -w 1: ftp://ftp.bsam.ru/pub/tmp/EeePC/netstat.ale.2
uname -a: ftp://ftp.bsam.ru/pub/tmp/EeePC/uname.2
kernel config:
-----
include         GENERIC
ident           EEEBB
 
nooptions       INVARIANTS
nooptions       INVARIANT_SUPPORT
nooptions       WITNESS
nooptions       WITNESS_SKIPSPIN

options         PSM_DEBUG=2

I've got similar results with age(4) at (FreeBSD host.ipt.ru 8.0-CURRENT

Both tests were just plain ftp session with big file transfer.
