    on the server kill the ssh server then restart it with the -d flag to put
    it into debug mode. This process will not fork and will write all debug
    output to the stderr (the window you started it from), then connect with
    winscp and try to duplicate the error you reported.

    it should give you some clues as to what is happening.

            Subject: ssh going zombie

        Using sshd under Debian Unstable Openssh 0.9.7e

        When winscp disconnects from our server the scp process goes zombie
    and the ssh process hogs the processor on the server. This only seams
    to happern with winscp and not with scp or ssh under linux. If the
    subprocess is removed from the sshd config file the a sub sshd process
    goes zombie instead and the calling sshd process hogs the processor.

        I'm think it may have somthing to do with the way winscp talks to
    sshd , but the winscp people seam to think this is a problem with sshd.
    I get this feeling this is going to be a problem nobody has a clue on
    and wishes to blame the other party.
