Hi Niphlod,
I changed my .conf file a littile by reading the web2py online book,
Created a new web2py-scheduler.conf file
start on runlevel [2345]
stop on runlevel [016]
respawn limit 8 60
script
exec sudo -u root python /srv/tv-fe/web2py.py -K app
end script
respawn
and another conf file tv-fe.conf
start on runlevel [2345]
# When to stop the service
stop on runlevel [016]
# Automatically restart process if crashed
respawn
respawn limit 5 60
# Specify resource limits
# Make sure you have set the system limits accordingly
limit nofile 65536 65536
# Modify scheduling priority, ranges from -20 (most favorable) to 19
(least
# favorable)
nice -10
# Out Of Memory (OOM) killing score, ranges from -999 (very unlikely to be
# killed by OOM killer) to 1000 (very likely) or 'never'
oom score -555
# Essentially lets upstart know the process will detach itself to the
background
expect fork
expect daemon
# Run before process
pre-start script
[ -d /var/log/tv/frontend ] || mkdir -p /var/log/tv/frontend
end script
# Start the process
script
exec python -- /srv/tv-fe/web2py.py --nogui -a '' -p 8000 -i 0.0.0.0
&
end script
The log from the upstart web2py-scheduler.log is

am I doing it the correct order, if yes then why doesnt the worker pickup
the task. I am not sure whether the conf files I have created is right.
I run the services as
sudo service tv-fe start
sudo service web2py-scheduler start
