[Ssh-sftp-perl-users] Help needed: Connection drops...

[CG <cg...@ya...>]

I'm having problems sending and receiving files to and from a server running
the commercial WinSSHD when I use Net::SFTP ... I can transfer the files using
OpenSSH's sftp client, though. I printed out the debug log, but everything
looks great until the end when it drops. It never gets to the end of the file,
even though it says that it received an eof. After the drop, the $sftp
connection is dead for the remainder of the script.

Here's the log...
