Hi,  
I have enable elasticsearch in my production chat application. There was total 500+ users that uses this application on daily bases for communication purpose. I have initialize ELS newclient once when server start and properly close response body of ELS. But I don't know why it established 20K tcp connection of ELS and it is increasing gradually with every post. Can anyone help me out from this issue?  
thanks.
