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;
