An Error Occurred While Starting Up The Preloader: It Did Not Write A Startup Response In Time.
Resetting RVM gemsets Unicorn vs Passenger Why can't Phusion Passenger extend my existing Nginx? Clone this wiki locally Clone in Desktop Sometimes an application refuses to startup. When this happens, Phusion Passenger reports one of these messages: An error occurred while starting up the preloader. It exited before signalling successful startup back to Phusion Passenger. An error phusion passenger is currently not serving any applications. occurred while starting up the preloader: it did not write a startup response in time. An error occurred while starting the web application: it did not write a handshake message in time. An error occurred while starting the web application. It exited before signalling successful startup back to Phusion Passenger. Phusion Passenger reports this error if the application did not finish initializing within a time limit, or if it exited without sending Phusion Passenger a message that says "I've initialized successfully!". The spawning process explained To understand what's going on, consider what Phusion Passenger does under the hood. Phusion Passenger spawns an application by running one of the following command: If your shell is bash: bash -l -c '/path-to/SpawnPreparer /path-to-loader-or-preloader' If your shell is not bash: /path-to/SpawnPreparer /path-to-loader-or-preloader So when launching your application, there are at most 4 components at work: If your shell is bash, then everything else is executed through bash, by passing the -l (login shell) flag to bash. This causes bash to load its start

And I found this FAQ on Phusion Passengers site The problem is that, when I try to use that command, passenger-config --root I get this: -bash: /usr/bin/passenger-config: ruby: bad interpreter: No such file or directory apache config: LoadModule passenger_module /usr/local/rvm/gems/ruby-1.9.3-head/gems/passenger-3.0.12/ext/apache2/mod_passenger.so PassengerRoot /usr/local/rvm/gems/ruby-1.9.3-head/gems/passenger-3.0.12 PassengerRuby /usr/local/rvm/wrappers/ruby-1.9.3-head/ruby

This feature reduces the chance of visitors experiencing any errors in case the deployment of an application update failed. Suppose that http://serverfault.com/questions/641681/cannot-checkout-session-because-a-spawning-error-occurred you have upgraded your application and you have issued a command to restart it, but the application update contains an error (e.g. a syntax error or a database configuration error) that prevents Passenger error occurred from successfully spawning a process. Passenger would normally display an error message to the visitor in response to this. By enabling deployment error resistance, Passenger Enterprise would "freeze" the application's process list. Existing application processes (belonging to the previous version) will be kept around to serve requests. The error is logged, but visitors do not see any error messages. Passenger keeps the old processes around until not spawn process an administrator has taken action. This way, visitors will suffer minimally from deployment errors. How it works When deployment error resistance is enabled, Passenger Enterprise would perform the following steps whenever it finds that it is unable to start an application process: It ensures that all requests are routed to existing application processes (that belongs to the previous version of the application). Passenger will not display an error message to the visitor. It logs the error to the log file. It sets an internal flag (Deployment Error Resistance Mode) so that no processes for this application will be spawned (even when the current traffic would normally result in more processes being spawned) and no processes will be idle cleaned. Processes could still be shutdown because of other events, e.g. because their memory limit have been reached. You can check whether Passenger Enterprise has entered Deployment Error Resistance mode by invoking passenger-status and checking for the message "Resisting deployment error" then the flag is set. Enabling the feature Deployment error resistance only works when a rolling restart is performed. So to enable this feature, we recommend that you set PassengerRollingRestarts on and PassengerResistDeploymentErrors on. Enabling deployment error res
