Identifying the max_children Limit Being Reached

To determine if any of your apps are hitting the max_children    limit, SSH in to your server as root and run the following    command:

sudo grep max_children /var/log/php?.?-fpm-sp.log.1 /var/log/php?.?-fpm-sp.log

If any of your apps have reached their max_children limit, you'll    see output like this:

[24-Apr-2017 19:56:17] WARNING: [pool my-wordpress-app] server reached max_children setting (20), consider raising it

It's look like TMD block the PHP-FPM max_children Setting.  It's not in the Cpanel.
