    Hi!
    Thanks Tomi, yes kill -9 my.script has been performed regularly. Seems
    to be a bad habit of mine, have to change it. Also, I may be doing wrong
    in the expect script, node simply is left in the dark?

    #! /usr/bin/expect -f
    # my.script
    # extract from the script giving an idea of what I am doing

    set timeout 600

    spwan node

    send "c some_node\r"

    expect timeout {
            exit 1
    } "onnected"

    logfile -a logfilename

    send "more stuff"

    expect timeout {
            exit 1
    } "someting_indicating_got_it_all"

    # end of script

    It leaves node connected to some_node. After script ends node
    disconnects the link but maybe have to tell that to the terminated
    script?

    It leaves the logfile to be closed by itself.

    I could add ctrl-T and bye to quit node in the script if that is the
    solution?
    Never thought it was a problem, till now ;-)

    clx 5.01 with postgrsql 6.5.1 have not (yet) complained.

    Thanks also Dirk and Richard.

    Thanks for the help,
    73, Kjell, sm7gvf
