Hi Dave,

Thank you for your script. Finally I've made it to work, although there still is one thing I don't understand...

Here is my version (the paths are just for testing):

description "Startup script for the web site"

  start on (local-filesystems and net-device-up IFACE!=lo)
stop on runlevel [016]

env PERL5LIB=/home/teddy/perl5/lib1/lib/perl5/i686-linux:/home/teddy/perl5/lib1/lib/perl5
env PATH=/home/teddy/perl5/perlbrew/bin:/home/teddy/perl5/perlbrew/perls/perl-5.14.2/bin:/home/teddy/perl5/lib1/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

export PERL5LIB
export PATH

expect fork

  respawn

exec /home/teddy/perl5/lib1/bin/starman --listen :5000 --workers 5 --max-requests 1000 --preload-app --pid /srv/log/site.pid --access-log /srv/log/access.log --error-log /srv/log/error.log --user teddy --group teddy --daemonize /srv/BRK/brk.psgi


I've also tried to exec a bash script that contains the same command above (without "exec") using:
exec /srv/BRK/start1.sh
But I don't know why it doesn't start the app this way.
If I exec the full command in the upstart script it works fine though.

I've seen that the app starts fine if I don't use the expect stanza, but in that case I can't close it using the stop command.
But I can start and stop it fine if I use either "expect fork" or "expect daemon".
