title: Express.js App on Phusion Passenger - did not write a startup response in time
body: <p>I am trying to run an express.js app on a server running Phusion Paggenger (apache) and am seeing the error "An error occurred while starting the web application: it did not write a startup response in time." after the request times out. I've read through <a href="https://github.com/phusion/passenger/wiki/Debugging-application-startup-problems" rel="nofollow">https://github.com/phusion/passenger/wiki/Debugging-application-startup-problems</a> but this seems a bit obscure. My express app is as bare-bones as possible so I'm wondering if anyone knows if there may be a component specific to express that might cause this. I have been able to run a plain node.js app with the same setup on the server. </p>
