Connection timeout for upstream server!

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, 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

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 :
