The nginx make proxy server...

  Some time was ok,some time :
[error] 18528#0: *50881 recv() failed (104: Connection reset by peer) while
reading response header from upstream, client: 222.178.73.129, server:
oa.owenschool.com, request: "GET / HTTP/1.1", upstream:
"http://10.2.4.33:80/", host: "oa.owens.com.cn" 

Why?  But some time is ok, some time is error....

The proxy config file:

 server {
        listen 80;
        server_name oa.owens.com.cn;
        location / {
            	root   html;
            	index  index.html index.htm;
                proxy_pass http://10.2.4.11;
                proxy_set_header   Host $host;
		proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For
$proxy_add_x_forwarded_for;
                proxy_set_header Accept-Encoding "";
		proxy_connect_timeout   60;
                proxy_send_timeout      60;
                proxy_read_timeout      60;
                proxy_buffer_size       512k;
                proxy_buffers           8 512k;
                proxy_busy_buffers_size 512k;
        }
	
  
        location = /50x.html {
            root   html;
        }

    
    }
