I’m in the process of setting up a replica server with hourly updates and have run in to a problem getting the web server to start correctly. I’m following the INSTALL.md documentation from GitHub.
The problem seems to be related to starting the web server as a service via Upstart (Ubuntu 14.04). If I start the web server as a non-root user from the command line, the web server starts normally and functions as expected. However, if I start the web server using the same command as the same non-root user via Upstart I get the following errors when I attempt to view the home page.
Log output of first web request after starting the app with upstart:

Anyone have an idea of what might be going on here?
