The issue I'm having is with the php-fpm lgging.   Excessive entries:

php-fpm: [08-Dec-2019 11:26:05] NOTICE: [pool inet] child 3717 exited with code 0 after 29.997416 seconds from start

These are every 30 seconds.  I have tried changing the logging from notice to warning with no change.  I have also changed the setting in /etc/php-fpm.d/www.conf from pm.max_requests = 5 to pm.max_requests = 500 with no change in behavior.
