    Possible to apply this setting to all domains with single file editing? I have lots of domains to be configured 1 by 1

    @Sharul Hafiz You can check the article mentioned in Additional Information section -
    Keep in mind that increasing of pm.max_children parameter for all domains can affect the server performance significantly. It is better to filter only affected domains in /var/log/plesk-phpXX-fpm/error.log file
    grep "server reached max_children setting" /var/log/plesk-phpXX-fpm/error.log
    and adjust max_children just for them.
