php-fpm unable to restart because of another FPM instance

Question

/etc/init.d/php-fpm restart
Stopping php-fpm:                                          [FAILED]
Starting php-fpm: [10-Oct-2013 21:24:37] ERROR: An another FPM instance seems to already listen on /home/php-fpm/sock/gosianozka.sock
[10-Oct-2013 21:24:37] ERROR: FPM initialization failed
                                                           [FAILED]

It happens from time to time and I don't have any idea how to fix it.

I'm using PHP 5.4.20 from ius repo on CentOS 6.4 64-bit.

Hard to give you a good answer here - there can be a lot of things to look at. Does the PID file exist? Is it taking too much time to kill all the children? When it happens, can you "stop" it without restart? When you have issued "restart" and it fails like that - will PHP-FPM eventually die after a while? — Frands Hansen, Oct 10 '13 at 20:56
Yes. It does. I'm unable to stop too. PHP-FPM continue to work despite this error. — Spacedust, Oct 11 '13 at 09:35
