upstream timed out

[Ruriko]

I have nginx as my web server with latest php 5.3.8. I run a scrapper script and I get this error

2011/09/03 07:39:36 [error] 1449#0: *1 upstream timed out (110: Connection timed out) while reading upstream, client: 58.174.129.205, server: [url]www.deliciousmanga.com[/url], request: "GET /wpm-crn/scp/?tkn=uVXcaozY70AfJgbVGy0z HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "www.deliciousmanga.com", referrer: "http://www.deliciousmanga.com/wp-admin/admin.php?page=wp-manga/mng/scp/mgr"

To fix this error I had to add

fastcgi_connect_timeout 60; 
fastcgi_send_timeout 180; 
fastcgi_read_timeout 180;

But when I do add these options it causes the site not responding all it does is load forever and in the end it would just say Bad gateway 504. The vps is running fine but it's just the site doesn't respond/load.

this is my nginx config

server {
    server_name www.deliciousmanga.com deliciousmanga.com;
    access_log /srv/www/deliciousmanga.com/logs/access.log;
    error_log /srv/www/deliciousmanga.com/logs/error.log;
    root /srv/www/deliciousmanga.com/public_html;

    location / {
        index index.html index.htm index.php;
    }

        location ~ \.php$ {
                include fastcgi_params;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                fastcgi_intercept_errors on;
                fastcgi_pass unix:/var/run/php5-fpm.sock;
        }

if (!-e $request_filename) {
  rewrite ^.*$ /index.php last;
}

fastcgi_connect_timeout 60; 
fastcgi_send_timeout 180; 
fastcgi_read_timeout 180; 
}
