This was working just the other day, but I just updated my code to the review server which runs Passenger 2.2.4 and my 2.3.4 rails app now can’t boot on that box.

Passenger reports:

Passenger encountered the following error:

The application spawner server exited unexpectedly: Unexpected end-of-file detected.

Exception class:
PhusionPassenger::Railz::ApplicationSpawner::Error

Any ideas?

    Figured it out. I finally checked the main apache error log and discovered there was a
    problem with one of my gems (facebooker config).

    To fix the facebooker issue, make sure there’s an entry for your environment in config/facebooker.yml

    I think passenger should at least give an option to see more of the stack trace that gets reported in apache’s error log. Would have been more helpful.
