PHP script executed twice on each request

[Katyo]

Binary package hint: php5-fpm

I wrote simple script /var/www/nginx-default/test.php with contents:

<?php

syslog(LOG_NOTICE, 'TEST.PHP RUN! '.time());
sleep(1);
syslog(LOG_NOTICE, 'TEST.PHP EXITED! '.time());

?>

Here is the part of my nginx config /etc/nginx/sites-available/default for php5-fpm:

location ~ \.php$ {
                root /var/www/nginx-default;
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include fastcgi_params;
        }

I can see next lines in my /var/log/syslog:

Apr 23 22:55:57 illumium php5-fpm: TEST.PHP RUN! 1303577757
Apr 23 22:55:58 illumium php5-fpm: TEST.PHP EXITED! 1303577758
Apr 23 22:55:58 illumium php5-fpm: TEST.PHP RUN! 1303577758
Apr 23 22:55:59 illumium php5-fpm: TEST.PHP EXITED! 1303577759

Hmm,

When I'm sniffing fcgi traffic between nginx and fpm with wireshark, I can see that nginx sends request twice.
Why it may be so?

Why invalid?
looks like a nginx / php issue (perhaps conf?)
But how to solve this?
