    Hello all.

    We are running OpenSSH 3.5p1 on Solaris 2.6 and 8 servers and some
    people sometimes gets a problem with hung connections.

    The easiest way to notice if when someone opens up a xterm window and by
    using -e executes ssh and in that way gets connected to a remote system.

    The person in question does some normal work, runs a few commands and so
    on and then by CTRL+D exits the session.

    The problem is that the connection to the other machine is not closed.
    ssh seems to be hanging there, with a force close of the xterm the
    problem is solved but some of my fellow workers gets a bit frustrated by
    this.

    I know this can happen if you start some daemon or background process
    and then try to leave the session but it happends in other cases as
    well.

    The logfiles has not been of any help at all even when set to debug
    level and I have no way of forcing this behaviour. I just thought I
    write out here and see if anyone else have experienced the problem.
