I see similar problem occur in Issue 842 , but I cant get it solved.

This line seems new:
Could not spawn process for group /path/to/my/project#default: An error occurred while starting up the preloader. It sent an unknown response type "socket: main;unix:/tmp/passenger.1.0.9635/generation-0/backends/ruby.GkRtJ56a9XUpxy7louRsCyEuAcqfLGcfGVMLiQz4a3yoxks;session;1\n".

I cant get a solution from https://github.com/FooBarWidget/passenger/wiki/Debugging-application-startup-problems

I think this is a duplicate of issue #1039 . It had already been fixed in commit 38afa8c, or version 4.0.32.
