nginx on windows keeps hanging

[asmith]

I'm new to this, please bare with me...

I'm running my fastcgi script using this .bat file: 

@ECHO OFF
D:\environments\php\php-cgi -b 127.0.0.1:9000 -c
D:\environments\php\php.ini
ping 127.0.0.1 -n 1>NUL
echo .
echo .
echo .
EXIT


So for my upstream, I modified it to: (duplicated that line 4 times.
will that work?)
@ECHO OFF
D:\environments\php\php-cgi -b 127.0.0.1:8004 -c
D:\environments\php\php.ini
D:\environments\php\php-cgi -b 127.0.0.1:8005 -c
D:\environments\php\php.ini
D:\environments\php\php-cgi -b 127.0.0.1:8006 -c
D:\environments\php\php.ini
D:\environments\php\php-cgi -b 127.0.0.1:8007 -c
D:\environments\php\php.ini
ping 127.0.0.1 -n 1>NUL
echo .
echo .
echo .
EXIT



and this is my latest nginx.conf:

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

    sendfile        off;

    keepalive_timeout  0;

  upstream myproject {
    server 127.0.0.1:8004;
    server 127.0.0.1:8005;
    server 127.0.0.1:8006;    
    server 127.0.0.1:8007;
  }
    server 
	{
        listen       3334;

        server_name  localhost;
        root   E:/emergency/HTML/;

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        location ~ \.php$ {

            fastcgi_pass   myproject;
            fastcgi_index  index.php;
            fastcgi_param PHP_FCGI_MAX_REQUESTS 0;
            fastcgi_param PHP_FCGI_CHILDREN 100;
            fastcgi_param  SCRIPT_FILENAME
$document_root$fastcgi_script_name;
            include        fastcgi_params;
        }
    }


I get those error still, but I think they are less now. Still irritating
though. I tried an ajax shoutbox script which fires requests every few
seconds and opened up 4-5 browsers to see the reaction. I have upstream
timeout errors. This time they haven't paralyze nginx but the errors
appear and ajax requests pend without any response. Lots of same error
on port 8006.

2012/05/19 23:22:31 [error] 1092#3704: *126 upstream timed out (10060: A
