Passenger: The application spawner server exited unexpectedly: Connection closed

Question

I was trying to deploy Redmine to Apache with mod_passenger on CentOS 6.3 but having the error :

The application spawner server exited unexpectedly: Connection closed

I installed the latest version (3.0.18) of passenger using gem.

After various failed attempts I decided to delete passenger from "gem uninstall passenger" and install it again using "yum install rubygem-passenger" instead. The installed version was "3.0.17"

Then it started working. Still don't know why exactly.

Answer 1

I also had same issue and figured out.

You may have RailsBaseURI directives in your apache config file. If you're using Rails 3, it should be changed to RackBaseURI.

See these

Answer 2

What other errors do you see in the log file?

Can you also try Phusion Passenger 4 beta from github's master branch?
