Unicorn / Capistrano, Post deploy Unicorn workers on new PID, app not refreshing

Question

So I've setup unicorn to restart post deploy on capistrano 3. It tells me it restarted OK, it has new PID's for workers, but when I refresh the app no change?

• I did a simple test and changed a small item in the view.
• If I do a "restart" on the server, it doesn't pickup the change.
• If I manually stop / start unicorn on the server it picks up the change.

What signal does this /etc/init.d/unicorn_salescrm_production use for restart?. For example, if you set preload = true, you should use USR2 instead of HUP for restart. http://unicorn.bogomips.org/SIGNALS.html
