Nginx CPU Issue : Remain at 100%

[Yogesh Sharma]

Team,

I am using nginx as Reverse proxy, where I see that once CPU goes up for
Nginx it never comes down and remain there forever until we kill that
worker. We tried tweaking worker_processes to number of cpu we have, but it
did not helped.

Any suggestion in this regards will help.

*Version:* nginx-1.10.1-1.el6

Below is the config:

user  nginx;
worker_processes  2;

pid        /var/run/nginx.pid;

worker_rlimit_nofile 65535;

events {
    worker_connections  15000;
}

http {

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

    log_format xxxxxxxxx';

    sendfile        on;

    server_tokens off;
    resolver 127.0.0.1 valid=30s;
    resolver_timeout 1s;
    keepalive_requests 75;
    keepalive_timeout  5 5;

    server_names_hash_bucket_size 128;
    server_names_hash_max_size 1024;

    proxy_buffers 4 32K;
    proxy_buffer_size 32k;
    proxy_connect_timeout 5s;
    proxy_read_timeout 305s;

    proxy_set_header Host $http_host;
    ignore_invalid_headers off;
    underscores_in_headers on;
    client_header_buffer_size 15k;
    client_body_buffer_size 16K;
    client_max_body_size 300M;
    send_timeout 305s;


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