525	Max connection limit too low (http_limit_conn_module)	Čeněk Zach		"Hello,

Trying to set 'per server' connection limit:

http:
  limit_conn_zone $server_name zone=perserver:10m;
location:
  limit_conn perserver 165000;

Getting error:
  nginx: [emerg] connection limit must be less '''65536''' in /etc/nginx/sites-enabled/

The limit seems to be hard-coded: 
  http://trac.nginx.org/nginx/browser/nginx/src/http/modules/ngx_http_limit_conn_module.c#L733

The nginx serves all content from single port (80). Is there a reason for this limit? Could it be raised/removed?

PS: Thanks for awesome server!"	enhancement	new	minor		nginx-module	1.5.x		connection limit http_limit_conn_module		Linux fra28.ff.avast.com 2.6.32-358.el6.x86_64 #1 SMP Fri Feb 22 00:31:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux	"nginx version: nginx/1.5.6
