New to nginx question about php-fpm

[adjc98]

I am new to nginx and had a question about php-fpm.  

It seems that php-fpm is being restarted at random times.  I am not sure
what is causing the restart, but when it does  I am getting this in the
php-fpm.log

[12-Jul-2015 00:52:29] ERROR: An another FPM instance seems to already
listen on /opt/pifpm/fpmsockets/5.5.11.sock
[12-Jul-2015 00:52:29] ERROR: FPM initialization failed

I am assuming that the error is happening because the FPM processes are not
being shut down correctly?

I am not sure how to find what is calling the FPM restart.  Do you have any
suggestions on how to find the initial restart call and how I can make it
restart smoothly?

The server is a centos server with cpanel.  I have not been able to locate
the php-fpm.conf  or the nginx.conf on my server.

I know you need more info than this, so please point me in the right
direction.
