<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
message</div>
<div>"Session did not start before timeout expired. Check
session logs." has it think the process is not ready.<br>

<div>Hi Sebastien, <br>
<br>
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
background, in the browser I have the ParaView
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>
Thanks<span><font color="#888888"><br>

<div>Hi Sebastien,<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
below.<br>
