Description:
------------
With the following parameters set in php-fpm.conf, FPM refuse to start properly. 
The worker threads are spawned, but hangs and only a kill -9 will stop them. 
Setting pm.max_children to a lower number works.

The exact config works with PHP 5.4.4.

pm = static
pm.max_children = 500

Discovered that I am experiencing the same problem with PHP 5.3.15 on Gentoo. php-
fpm refuses to start correctly. It hangs although the child processes are started 
and continue to work even after kill -9 on the main command 
/usr/lib/php5.3/bin/php-fpm -y /etc/php/fpm-php5.3/php-fpm.conf -g /var/run/php-
fpm-php5.3.pid 

Changing the pm.max_children did not seem to fix this for me and I am using pm = 
dynamic.

Works fine with PHP 5.3.14
