Could you try very simple config with small application from passenger
distro, i.e. something like this.

http {
include mime.types;
default_type application/octet-stream;

passenger_root /usr/local/rvm/gems/ruby-1.9.2-p136/gems/passenger-3.0.9;
passenger_ruby /usr/local/rvm/wrappers/ruby-1.9.2-p136/ruby;
passenger_default_user www;

server {
listen 127.0.0.1:80;
server_name localhost;

root /usr/local/rvm/gems/ruby-1.9.2-p136/gems/passenger-3.0.9/test/stub/rack/public;
passenger_enabled on;
passenger_use_global_queue on;
}
}

After restart your nginx with passenger you should find nginx and passenger
processes.

% ps auxww | grep nginx | grep -v nginx
root 18932 4,0 15,9 44464 39656 ?? Ss 8:46 0:00,01 nginx: master process /usr/local/sbin/nginx
www 18933 4,0 16,0 44464 39904 ?? S 8:46 0:00,02 nginx: worker process (nginx)
% ps uaxww | grep -i passenger | grep -v grep
root 18923 0,0 1,0 5760 2508 ?? Is 8:46 0:00,07 PassengerWatchdog
root 18926 0,0 1,5 15052 3820 ?? I 8:46 0:00,09 PassengerHelperAgent
root 18929 0,0 2,7 13176 6620 ?? I 8:46 0:01,75 ruby: Passenger spawn server (ruby)
nobody 18930 0,0 1,4 6688 3600 ?? I 8:46 0:00,07 PassengerLoggingAgent

% telnet 127.0.0.1 80

Does it possible reproduce your problem for simple configuration?
