Crazy Passenger on board

I don’y know where to look for more information now…

I am running a Rails app on server A ( Debian5 (Lenny) / Plesk 10.1 -
rvm - Passenger 3.0.7)
no problem …
console … :
root 2592 0.0 0.0 88856 1888 ? Ssl Jul22 0:00
PassengerWatchdog
root 2595 0.1 0.0 97824 2548 ? Sl Jul22 1:23
PassengerHelperAgent
root 2597 0.0 0.0 45292 9656 ? Sl Jul22 0:46
Passenger spawn
server
nobody 2601 0.0 0.0 73180 3804 ? Sl Jul22 0:00
PassengerLoggingAgent
vhost:
/var/www/vhosts/seveacademy.com/conf/vhost.conf ( this is Plesk …
used into httpd generation)
ServerName seveacademy.com
DocumentRoot /var/www/vhosts/seveacademy.com/rails/testsbga/current/
public
RailsEnv “production”
<Directory “/var/www/vhosts/seveacademy.com/rails/testsbga/current/
public”>
AllowOverride All
Options Indexes FollowSymLinks -MultiViews

now I am running another rails app on another brand new server B
(Debian6(Squeeze) / Plesk 10.2- rvm - Passenger 3.0.7) same rails
( 3.0.9 , same gems installed , same ruby 1.9.2)
console :
root 18789 0.0 0.0 23404 1928 ? Ssl 12:03 0:00
PassengerWatchdog
root 18792 0.0 0.0 97696 2192 ? Sl 12:03 0:00
PassengerHelperAgent
root 18794 0.0 0.2 42280 8508 ? Sl 12:03 0:07
Passenger spawn
server
nobody 18798 0.0 0.0 74636 3936 ? Sl 12:03 0:00
PassengerLoggingAgent
vhost:
/var/www/vhosts/mysportacademy.com/conf/vhost.conf ( this is Plesk
too … used into httpd generation)
ServerName mysportacademy.com
DocumentRoot /var/www/vhosts/mysportacademy.com/rails/rapsberry/
current/public
RailsEnv “production”
<Directory “/var/www/vhosts/mysportacademy.com/rails/rapsberry/current/
public”>
AllowOverride All
Options Indexes FollowSymLinks -MultiViews

this application is running fine in localhost, the domain is ready
( capistrano deployment OK)
the application is in place in /var/www/vhosts/mysportacademy.com/
rails/rapsberry/current/public
BUT
when going to the URL http://mysportacademy.com it reaches the
standard httpdocs index html

what could I do get some more information on what could be missing in
this new server … ??
thanks for your suggestions

as I don’t know if it’s rails , passenger , or rvm, I am going to ask
for help also in rvm and passenger groups
