I have made this upstart script, which starts a Node.js service. But all of the sudden the service has stopped, and upstart has failed to restart it. Now that I am trying to start it manually, it fails to recognize my service:

start: Unknown job: queue

The script is properly placed in /etc/init, and should have the correct rights:

-rw-r--r--   1 root root  200 Aug  7 13:30 queue.conf

When I check the config file with init-checkconf however, it says that it is not able to run as root:

root@production1:~# init-checkconf /etc/init/queue.conf 
ERROR: cannot run as root

What causes this error and how do I solve it?

Debug info:

Ubuntu 12.04.3 LTS

root@production1:~# service --version
service ver. 0.91-ubuntu1

Edit

Here's queue.conf:

description "Echo.it command queue"
author      "Ronni Egeriis Persson <[email protected]>"

stop on shutdown
respawn
respawn 20 5

exec sudo -u beanstalk /usr/bin/node /var/www/queue/index.js >> /var/log/queue.log 2>&1

The command sudo -u beanstalk /usr/bin/node /var/www/queue/index.js >> /var/log/queue.log 2>&1 works fine when run manually.
