PHP FPM Keeps Eating Memory Until My Website Crashes

I have a server with 30 GB RAM, 800 GB SSD & 8 CORES. I am using WHM & CPANEL, When I Turn on PHP FPM For my Website from WHM then the PHP FPM Keeps Eating All the Memory ( upto 30 GB ) & Finally My Website Crashes. My System PHP FPM Configuration is : 800 Max Requests, 250 Max Children, Process Idle Timeout: 30 I tried changing this configuration, But It just makes the eating of memory slow or fast ( But It reaches 30 GB & Crashes my Website ). If I turn off the PHP FPM, Then My Server Load Increases Automatically and goes up to 25 but the Memory is always under 4 GB. So Currently I have Turned off the PHP FPM. I am using Apache. What is the solution for this? Please help.

  Have you checked the PHP-FPM error logs for any indication of what is going on when PHP-FPM is consuming more memory than anticipated? The error logs are located per PHP version in the following location: /opt/cpanel/ea-phpXX/root/var/log/php-fpm/error.log
