Phusion Passenger preloader error nginx

Question

I'd like to thank you in advance for helping me out with this. I am going mad here trying to figure out what is wrong with phusion passenger or my rails app.

I have done a lot of googling as well as read everything on https://github.com/phusion/passenger/wiki/Debugging-application-startup-problems but i still can not seem to figure out what the problem is.

I have included where i think the problem lies but the full error can be accessed at www.malikhandaan.com.

Thank you so much for helping, in advance.

(I am newbie at rails, this is my first app deploy with nginx)

Answer 1

After much research and plugin all night at this i found that ruby-2.0.0 seems to have this error as i downgraded to ruby-1.9.3 the problem was resolved.....i moved from one problem to another...at least i am past this one. :)

Hope this helps any newbie to rails.
