Hello,

I am using nginx as a load balancer in front of a tier of 4 web  
servers in a configuration very similar to:

[Simple Load Balancing | NGINX](http://wiki.nginx.org/LoadBalanceExample)

I am doing rolling deployments of my application on the 4 web servers.  
During a deploy, I take 2 of my 4 boxes out of the load balancer by  
switching to an alternative nginx configuration and running ‘nginx  
reload’. This has so far worked well.

One thing I noticed is that when I do this, nginx seems to snap  
(break) any connections that were open at the time of the reload. Is  
there a configuration setting that I could use to allow these  
connections to complete gracefuly, but otherwise have all new  
connections be handled according to the updated configuration?

Best Regards,

Kyle Burton
