2285	"strange ""worker_connections are not enough, reusing connections"" warning"	gabriel.dodan@…		"Hi,

I keep getting that warning, although according to nginx configuration i shouldn't. This is my configuration  

{{{
user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


worker_rlimit_nofile 120000;
events {
    worker_connections  10000;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] ""$request"" '
                      '$status $body_bytes_sent ""$http_referer"" '
                      '""$http_user_agent"" ""$http_x_forwarded_for""';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

}}}

The server has 12 cores , so according to nginx configuration the nginx server should handle up to 120000 connections. I have activated stub_status and it shows 6190 active connections . So I should no get that warning because active connections are way less than what nginx is configured to handle. 

this is the exact warning i get 

{{{
2021/11/26 13:50:23 [warn] 114001#114001: 10000 worker_connections are not enough, reusing connections
}}}

I use nginx mainly as proxy, proxied servers are websocket servers

Any idea? 

Thanks and regards!
