For upstream keepalive to work you have to enable keepalive 
connections on backend server(s).

If you are using nginx on backend - you have to use 
keepalive_timeout to enable keepalive support on it.

p.s. Your question is clearly unrelated to the patch about dead 
servers recheck.  Please don't hijack unrelated threads.  Thank 
you.
