php-fpm virtual memory
I always get this triggered report comes to my email many times a day.
Account: bizzindex
Resource: Virtual Memory Size
Exceeded: 520 > 512 (MB)
Executable: /opt/cpanel/ea-php74/root/usr/sbin/php-fpm
Command Line: php-fpm: pool bizzindex_com
PID: 20055 (Parent PID:1504)
Killed: No
I adjusted the memory size in WHM to 2048 and php.ini to 1024mb but, it did not seem to help.
What is the best solution? Thanks

Hello! There can be multiple places to change the PHP memory limit, and PHP-FPM has it's own configuration file, usually at /etc/phpX/fpm/php-fpm.conf where "phpX" is your version of PHP. There's a Stack Overflow post with further suggestions here:

Since the OP mentions php 7.4:
Executable: /opt/cpanel/ea-php74/root/usr/sbin/php-fpm
On Debian/Ubuntu, since the advent of PHP 7 or so, php.ini has been centralized in a single place /etc/php:
- /etc/php/<version>/cli/php.ini
- /etc/php/<version>/apache2/php.ini
- /etc/php/<version>/fpm/php.ini
where <version> is the PHP version number and {cli, apache2, fpm} are the operational php.ini's for the command-line, the apache2 plug-in and the fastcgi process manager, respectively.
PHP comes with two native functions to show which config file is loaded:
- php_ini_loaded_file returns the path of the loaded .ini file; and
- php_ini_scanned_files returns a list of .ini files parsed from the additional .ini directory.
You can try each one of these out with something like:
php -r 'echo php_ini_loaded_file();'
