nginx version: nginx/1.2.0
built by gcc 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu3) 
TLS SNI support enabled
configure arguments: --add-module=/tmp/chunkin --with-http_ssl_module
--with-http_sub_module --with-http_gzip_static_module
--with-http_stub_status_module --with-pcre --prefix=/usr/local/nginx

Number of connections in the 35000 normal, the number of connections up
to 40 000, nginx the status url can sometimes open sometimes not open
,other url is such a situation.Open nginx the status url, refresh a few,
how does that matter?
nginx configuration is as follows:

user www-data;
worker_processes  8;

error_log  /var/log/nginx/error.log;
pid        /var/run/nginx.pid;
worker_cpu_affinity 00000001 00000010 00000100 00001000 00010000
00100000 01000000 10000000;
worker_rlimit_nofile 655350;
events {
	use epoll;
	worker_connections 51200;  
}

http {
    charset  utf-8;
    include       /etc/nginx/mime.types;

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

    sendfile       on;
    tcp_nopush     on;
    keepalive_timeout  60;
