My nginx configuration works fine, but suddenly after some time (mostly  
days) he begins to answer 3x and the error occurs in the log below for  
all  
requests:

2012/09/13 17:15:35 [error] 26027#0: \*4923 rewrite or internal  
redirection  
cycle while processing “/index.php”, client: 201.26.2.XXX, server:  
www.XXX.com.br, request: “GET /checkout/cart/ HTTP/1.1”, upstream:  
“fastcgi://unix:/var/run/php5-fpm-xxx.sock:”, host: “www.XXX.com.br”,  
referrer: “[BOOKROSA](http://www.XXX.com.br/product-xxx.html)”

The error only after I reload nginx configuration with  
“/etc/init.d/nginx  
reload”

What can it be?

My host config:

server {  
listen xxx.com.br:80 default;

server\_name www.xxx.com.br \*.xxx.com.br;

My best guest is that somebody removes /index.php (to replace it  
with a new one?) + open\_file\_cache (configured at global level?) +  
the fact that there is infinite loop in your config if there is no  
/index.php.

Thanks for the reply, but do not know if this is the problem because the  
open\_file\_cache is not configured at global level, and index.php is not  
changed or replaced, this file was never changed because it is the  
default  
magento, have any other ideas of what might be?

I appreciate the help …

May be a result of X-Accel-Redirect loop if your backend use it, or  
backend error + fastcgi\_intercept\_errors + error\_page loop (again  
if configured).

If in doubt, you may activate debug log (see  
[A debugging log](http://nginx.org/en/docs/debugging_log.html)). From debug log it  
would be clear what exactly goes on.
