i described this problem a week or so ago, but the solution that i
thought had solved it hasn't fully fixed it.

problem:

ftp transfers (with wu-ftpd) randomly hang.

i set up a web server that mirrors the contents of the ftp directory
and the exact same file retrieved via http works perfectly!

here's the ftp client error, from ncftp (regular ftp just hangs
forever).

Receiving file: scyberbo.mov
 79%  0 =================================>          3360313 bytes. ETA:  0:05
Error: Error occurred during read!
Reason: Operation timed out
** Aborting Transfer **
Transfer aborted. Data connection closed.

the solution proposed was to disable tcp_extensions.  this i have done
but it made no difference.  here's my tcp config, in case it helps:

net.inet.tcp.rfc1323 = 0
net.inet.tcp.rfc1644 = 0
net.inet.tcp.mssdflt = 512
net.inet.tcp.stats: unknown structure returned
net.inet.tcp.rttdflt = 3
net.inet.tcp.keepidle = 14400
net.inet.tcp.keepintvl = 150
net.inet.tcp.sendspace = 16384
net.inet.tcp.recvspace = 16384
