We have a page that should deliver XML. We have newly upgraded ruby from 1.9.3 to 2.2.2 and rails 3.2.17 to 4.2.1
Our server is using nginx and passenger to receive requests

When we are access our server and get the XML we get the respond 
notice that all other pages is working

When we are doing this in development environment it all works good, it still take time. If we use less data it work on server and on development. And it nota specific point it breaks.

example 
    5 bank transaction always work 
  50 bank transaction work from time to time like 5 out of 10 
100 bank transaction never work

I have tried to downgrade ruby version to 2.1.0, no luck there. Alse I tried to downgrade ruby version to 2.0.0, it works a lot better but still not all the time.

Why?? I thing it is something with passenger and ruby 2.1 and 2.2? 
what i can to to keep using ruby 2.2.2
