96	Default_server catch all block not working	www.google.com/accounts/o8/id?id=AItOawnxEpaUM9BjPLuvymmX1VMwI3fyJckZUx0	somebody	"Nginx after a Load Balancer and proxying Apache php site behaves in a strange way when defining a default_server catch-all  block.
Scenario :: Only one site-enabled with several server blocks defined on it. Each server has plenty of server_name (as ServerAlias does have the underlying apache). Next block is defined at the very beggining of site-enabled/onlysite :


{{{
server {
  listen 80 default_server;
  server_name _;
  proxy_intercept_errors on;
  error_log /var/log/nginx/000default-error.log debug;
  access_log /var/log/nginx/000default-access.log;
  return 444;
}

}}}

Result:
.- As soon as i enable the above block, Server seems to respond Ok, returning 444 to every request like ''nonexistantsubdomain.mydomain.com''  but the 000default-access.log starts to be filled with:
    ..-[A] Plenty of requests which souhld be ok responded with the 444 code
    ..- [B] Plenty of strange request like this ::: [01/Feb/2012:12:13:40 +0100] ""-"" 400 0 ""-"" ""-""

.- In less than 3 minutes, suddenly the above access log stops receiving that bunch of 444 responded requests[A] and it only shows the [B] from time to time (some buffer overloaded?). From that moment on, any request gets error as reponse."	defect	closed	major		nginx-core	1.1.x	worksforme	default_server 444		Linux web2.forvo.com 2.6.32-5-xen-amd64 #1 SMP Wed Jan 12 05:46:49 UTC 2011 x86_64 GNU/Linux	"nginx version: nginx/1.1.8
