We’re having following issue with nginx and php-fpm, please have a look  
on  
logs :

2013/12/26 16:43:24 [error] 9906#0: \*37001 upstream timed out (110:  
Connection timed out) while reading response header from upstream,  
client:  
192.252.214.240, server: [search.com](http://search.com), request: “GET  
/search/es/index\_video.php?videoid=1593251&is\_updated=yes HTTP/1.1”,  
upstream: “fastcgi://127.0.0.1:9000”, host: “[search.com](http://search.com)”

Also tried increasing proxy timeout to 300 from nginx. When we telnet  
the  
port 9000, connection automatically closed after 4~5 seconds :

Trying 127.0.0.1…  
Connected to 127.0.0.1.  
Escape character is ‘^]’.  
Connection closed by foreign host.

we’ve also found slow logs in php-fpm :
