Description:
------------
Hi, I wrote a small testprogram to test performance with php-cgi running in fastcgi mode and keep getting Errors. When I run it, the program fails first after 137 requests. 

The test program continues then and succeeds on the next requests but fails totally after 273 Requests. No response comes back from the php-cgi binary.

I started php-cgi with following command:

/opt/www/php/bin/php-cgi -b 127.0.0.1:9000

Environment Variables for php-cgi:

PHP_FCGI_CHILDREN = 27
PHP_FCGI_MAX_REQUESTS = 10000000

Reproduce code:
---------------
You can find the test program here:

I tested with following test.php:
<?php
echo "Hello World!\n";
phpinfo();
?>

Expected result:
----------------
The same output for all requests without any errors.

Actual result:
--------------
From the cgi binary I get following response for Request 137
