              </div>
              <div>The short answer is that the "ready_line" property
                inside your launcher.json file should be "Starting
                factory" and not "Starting factory - XYZ" for all the
                command lines. (Like written in the documentation ;-)</div>
              <div><br>
              </div>
              <div>The reason is that the launcher look for that exact
                String in the output of the process that it runs. This
                allow to know when the process is ready. And the line
                "Starting factory - XYZ" never show up, hence the error

                          OK, I finally upgrade to Ubuntu 14.04 and
                          apache 2.4! however, I still have some issue.
                          again I see the render window pop up in the

                          web logo and spinning wheel, now after a few
                          seconds a dialog: Session did not start before
                          timeout expired. Check session logs.<br>
                          <br>
                          I cranked up the log verbosity in apache.
                          attached everything.  Any idea what the
                          problem is? how to get more info? paraview has
                          an error, how does that get reported?<br>

                                        <br>
                                        this is for a public deployment
                                        but I am testing in the browser
                                        while it locally logged into the
                                        system. This server is running
                                        ubuntu 11.04, apache 2.2.22. I
                                        hope that this isn't a
                                        roadblock.I can't easily
                                        upgrade.<br>
                                        <br>
                                        your instructions for 14.04 went
                                        off OK but in 2 spots I had to
                                        find a work around:<br>
                                        1) proxy_wstunnel had to be
                                        installed manually, this went
                                        without a hitch and it loaded up
                                        without error<br>
                                        2) in the apache config I had to
                                        comment #Require all granted as
                                        that wasn't valid in 2.2<br>
                                        <br>
                                        the session id was in the
                                        proxy.txt file and had the port
                                        number 9100 which I see
                                        elsewhere in the logs, so that
                                        looks OK.<br>
                                        <br>
                                        I'm attaching the launcher
                                        config.<br>
                                        <br>
                                        the apache config is pasted

                                                    <br>
                                                    Seems that the
                                                    problem potentially
                                                    relates to web
                                                    sockets. How can I
                                                    get further info
                                                    about what's
                                                    failing? Can anyone
                                                    give some hint on
                                                    troubleshooting this
                                                    issue?<span><font
