Mysterious FTP failure

Ive been using cygwins ftp.exe client program on my NT 4.0 SP 6
machine for quite a while. Its
worked flawlessly for months. I have not made any changes to the box and
have not upgraded any
cygwin components in months. Sometime in the last 48 hours something
changed. Now when
I attempt to ftp a tar file, it sends about 98-99% of it or so, and then
mysteriously quits thinking
it had sent the whole thing. (It does not report any transmission
errors). Its not tar, because if I
ftp TO the box via inetd/ftpd and retrieve the file the whole thing
transfers just fine. Ive rebooted the
box numerous times, as well cold shutdown (to reset the network card)
same problem. I havent
tried uninstalling or reinstalling any cygwin components, because Id
really like to understand whats
CAUSING the problem. Im writing automation software that has advanced
error checking and Id
like to trap and identify this condition (if possible) and advise in
an error message what the possible
genesis of the condition is and what hints one can follow to remedy
and/or prevent the problem. The
automation software essentially automates cross-network unix
command-line environments and is
100% perl. As such, it relies on cygwin for this environment on MSWin
boxes. If one node fails it
can switch boxes automatically but being able to determine WHY a box
has a problem and reporting
it successfully is VERY important to the overall approach of the
software.
If anyones got a clue whats happened to break ftp or can suggest
what other things I can investigate
to get the bottom of this problem Id REALLY appreciate it.
