Hi Dustin, Sounds like an environment issue. Take a look at:
http://upstart.ubuntu.com/cookbook/#job-environment http://upstart.ubuntu.com/cookbook/#see-the-environment-a-job-runs-in http://upstart.ubuntu.com/cookbook/#checking-how-a-service-might-react-when-run-as-a-job http://upstart.ubuntu.com/cookbook/#determining-why-your-service-fails-to-start At a guess, I'd suggest that supervisord is expecting one or more environment variables to be set, but not finding them and behaving erratically as a result. If you're running on Ubuntu or Debian, try installing my procenv tool and diff'ing the logfiles in a "good" and "bad" environments (as shown in the last link above) to help you track down the root cause. Kind regards, James. 2014-03-17 18:21 GMT+00:00 Dustin Oprea <[email protected]>: > This is an error having to do with a combination of Upstart and > supervisor.
