nginx fastcgi continued..

I'm on ubuntu hardy heron, 2.6.24-19-server 64 bit
nginx/0.5.33
django 1.0.2
Python 2.5.2
mysql 5.0.51a-3ubuntu5.4
Here's how I installed everything from the beginning
http://pastie.org/515408
Here's how I restart my django app
#!/bin/sh
if [ -f /var/www/django/conf/pid/$1.pid ]; then
echo stopping $1 site
kill `cat /var/www/django/conf/pid/$1.pid`
else
echo $1 was not running
fi
/usr/bin/python /var/www/django//$1/manage.py runfcgi method=prefork
minspare=1 maxspare=1 socket=/var/www/django/conf/sockets/$1.sock
pidfile=/var/www/django/conf/pid/$1.pid
chmod 777 /var/www/django/conf/sockets/$1.sock
Here's the server directive in the /etc/nginx/sites-available/default file
server
{
listen 80;
server_name $1.com;
access_log /var/www/django/log/access.log;
error_log /var/www/django/log/error.log error;
location /
{
fastcgi_pass unix:/var/www/django/conf/sockets/$1.sock;
fastcgi_param SERVER_NAME $server_name;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param PATH_INFO $fastcgi_script_name;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_pass_header Authorization;
fastcgi_intercept_errors off;
}
}
Here's the /etc/nginx/nginx.conf
user username groupname;
worker_processes 6;
error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
access_log /var/log/nginx/access.log;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
tcp_nodelay on;
gzip on;
include /etc/nginx/sites-enabled/*;
}
Every now and then the web site returns a 502 bad gateway error. It's
a very small site with hardly any traffic, so resources are not a
problem. It usually happens immediately after I restart the site with
the script above, I'm wondering if the restarting is a problem.
Here's what nginx says about it, running in error mode
2009/06/17 17:09:22 [error] 17715#0: *10888 connect() to
unix:/var/www/django/conf/sockets/$1.sock failed (111: Connection
refused) while connecting to upstream, client: 82.15.29.187, server:
servername, URL:
"/news/2009/jun/09/summer-fund-now-open-applications-continuing-stude/",
upstream: "fastcgi://unix:/var/www/django/conf/sockets/$1.sock:",
host: "servername", referrer: "http://somewebsite.com/"
I've switched file caching on now in django, so I'm not getting any
errors any more, but I need to understand what is causing those
errors, for my own sanity if nothing else
I can get any log information if needed, and perform any tests. I
think I've got something setup slightly wrong, but I have no idea what
it is.
If anyone can shed any light on the topic I'd be most grateful.

Hi Matt,
Your issue seems oddly familiar to me but I forget how I fixed it. I'm
running nginx-0.7.34 built from source and django trunk Rev: 10558. I would
try doing a source build of the current release of nginx which is 0.7.60
first to see if that fixes it. The fastcgi_params are also picky so check
those too.
Here's how I start mine up.
su -m -c 'python /var/django/projects/gis/manage.py runfcgi
--settings=gis.settings method=prefork pidfile=/tmp/django.pid
host=127.0.0.1 port=8800' nobody /bin/sh
NGINX conf:
location /viewer/ {
fastcgi_pass 127.0.0.1:8800;
include fastcgi_params;
fastcgi_pass_header Authorization;
fastcgi_intercept_errors off;
}
and my fastcgi_params are:
fastcgi_param PATH_INFO $fastcgi_script_name;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;
