Help with debugging upstart script

[James Hunt]

Hi Thomas,

Have you seen the following?

- https://lists.ubuntu.com/archives/upstart-devel/2014-February/003036.html
- https://github.com/pivotalsoftware/newrelic_pivotal_agent (includes an
example upstart job configuration file)

It appears that the plugin is forking more than twice which is why you are
experiencing the issues. This may be a bug in the plugin, or possibly it is
spawning off multiple "worker processes" once it has finished initialising.
If the latter, ideally, it would send itself SIGSTOP when ready which would
allow the upstart job to specify 'expect stop' (see
http://upstart.ubuntu.com/cookbook/#expect-stop).

Regards,

James.
