i'm having some problems with nginx. I think it's easy to solve, but i'm extremely newbie in nginx, so:

When worker_connections reach limit, nginx return a 500 internal server error. I want to customize this page, but error_page doesn't work =/

On error log:

[alert] 32194#0: *10 4 worker_connections are not enough while connecting
to upstream, client: X.X.X.X, server: example.com, request: "GET / HTTP/1.1",
upstream: "fastcgi://", host: "example.com"

and my nginx.conf:

worker_processes  4;

error_log  /var/log/nginx/error.log;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;

http {
    include       mime.types;
    default_type  application/octet-stream;
        proxy_intercept_errors on;
        proxy_next_upstream error timeout http_500 http_503;

    sendfile        on;
    keepalive_timeout  65;

    gzip on;
    gzip_http_version 1.0;
    gzip_comp_level 2;
    gzip_proxied any;
    gzip_min_length  1100;

    gzip_disable "MSIE [1-6].(?!.*SV1)";
    gzip_vary on;

    server {
        root /var/www/default/public/;
        server_name example.com;
        listen X.X.X.X:80 default;
        server_name_in_redirect off;
        server_tokens off;
        log_not_found off;

        error_page 404 /index?$uri;
            error_page 403 /restricted;
            error_page 401 /restricted;
                error_page 500 /50x.html;

                location = /50x.html {
                        root /var/www/default/public/;

        gzip on;
        gzip_types text/css application/x-javascript text/richtext image/svg+xml text/plain text/xsd text/xsl text/xml image/x-icon;

        location / {        
            error_page 404 /index?$uri;
            charset utf-8;
            if_modified_since off;

            add_header X-UA-Compatible "IE=Edge,chrome=1";
            add_header X-Powered-By "";
            add_header ETag "";

            index index.php index.html index.htm;

        location ~ \.php$ {
            include fastcgi_params; 
            fastcgi_index index.php; 
            fastcgi_param SCRIPT_FILENAME /var/www/default/public$fastcgi_script_name; 
            fastcgi_param SERVER_NAME $http_host;
            fastcgi_ignore_client_abort on;
            fastcgi_intercept_errors on;
            error_page 404 /404;

Try creating an error_page at the http section and see if that triggers. I guess hitting worker limit means server sections won't be parsed at all.
