    We're copying a number of files, sometimes up to 3-400, using
    scp called from a perl script. The command issued by the perl script is:

            my $cmd = "scp $basedir/data/$basename remote.example.com:/tmp";
            system ($cmd);

    We're finding that some ssh processes, with a PPID of 1, remain after the
    script has completed. "ps -ef" shows:

    UID PID PPID C STIME TTY TIME CMD
    root 12904 1 0 09:35 pts/0 00:00:00 /usr/bin/ssh -x ...
    root 12990 1 0 09:36 pts/0 00:00:00 /usr/bin/ssh -x ...
    root 12995 1 0 09:36 pts/0 00:00:00 /usr/bin/ssh -x ...
    root 13000 1 0 09:36 pts/0 00:00:00 /usr/bin/ssh -x ...
    root 13251 1 1 09:37 pts/0 00:00:00 /usr/bin/ssh -x ...

    The full command shown in each case (removed from above to prevent line
    wrapping) is:

    /usr/bin/ssh -x -oFallBackToRsh no remote.example.com scp -t /tmp

    I've tried "shopt -s huponexit" but that hasn't resolved this. Can anyone
    shed some light on why this is happening and how we can fix it?

    Thanks for any help or ideas.

    Sue
