Nginx Connections dipped on reload

[kamalakarv]

Our Setup:
  * We are using Nginx as load balancer and using ip_hash
  * Two backend nodes with each can accept  'x' connections and Nginx
connections are '2x'
  
Yesterday we had huge traffic so decided to increase backed node
connections so increased it  by 'y' and restarted backend nodes and
reloaded the Nginx . We have Observed that Nginx connections dipped on
reload? 

Why Nginx connections dipped on reload ? any idea?

Thanks
Kamalakar
