Timeout serving large requests

[BrindleFly]

Here is nginx version (note: although it is compiled with passenger, I have
not turned on the passenger directive in nginx.conf):

nginx version: nginx/1.2.6
built by gcc 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) 
TLS SNI support enabled
configure arguments: --prefix=/etc/nginx --with-http_ssl_module
--with-http_gzip_static_module --with-cc-opt=-Wno-error
--add-module=/usr/local/rvm/gems/ruby-1.9.3-p286/gems/passenger-3.0.18/ext/nginx

Here is nginx.conf:

user nobody;
worker_processes  1;
pid /etc/nginx/nginx.pid;

events {
  worker_connections  1024;
  accept_mutex off;
}

include conf.d/*.conf;

http {
  upstream app_server {
    server 127.0.0.1:8080 fail_timeout=0;
  }
  server {
    listen 80 default;
    server_name myapp.com;
    root /var/www/myapp/public;

    try_files $uri/index.html $uri.html $uri @app;

    location @app {
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

      proxy_set_header Host $http_host;

      proxy_redirect off;

      proxy_pass http://app_server;
    }

  }
