Problem with deploying changes in production

Problem with deploying changes in production.

In my /config/environment/production.rb, if I have:
config.cache_classes = false
and I run “ruby script/server -e production”
I can see my new changes.

When I change the /config/environment/production.rb back to:
config.cache_classes = true
and kill and restart the server with “ruby script/server -e
production”
the changes are not there. Some how, the old code is still there.

Any help would be appreciated.
