Issue Setting max_children in Plesk GUI is strange

[Azurel]

I found in /var/log/plesk-php73-fpm/error.log this lines:

[pool domain.tld] server reached max_children setting (100), consider raising it

So I want change it and found: How to customize PHP-FPM pool settings for a domain through Plesk?

I take a look in Plesk > Domains > domain.tld > PHP Settings.

As you can see, plesk says 20 and not 100.

I looked in php.ini of domain.tld and its says again 100.
/var/www/vhosts/system/domain.tld/conf/php.ini

[php-fpm-pool-settings]
pm.max_children = 100
pm.start_servers = 20
pm.min_spare_servers = 20
pm.max_spare_servers = 35

Why have plesk gui complete different values? Yes I'm in correct domain.
I have looked in other domains and default is "5", but in php.ini of this domain its again a value of "100".
Plesk Onyx Version 17.8.11 Update #74

usually (Centos & Ubuntu) the php.ini for the domains are located under: /opt/plesk/php/7.x/etc/php-fpm.d/ and there you will get / see the settings from the gui

afaik a manual added php.ini under /var/www/vhosts/system/domain.tld/conf/php.ini will not be updated / changed by the gui settings

Oh, I forgot this part to insert (again) in my posting. (first try on support-page was killed)

/opt/plesk/php/7.3/etc/php-fpm.d/domain.tld

; Following directives define pool configuration
pm = ondemand
pm.max_children = 100
pm.max_spare_servers = 35
pm.min_spare_servers = 20
pm.process_idle_timeout = 10s
pm.start_servers = 20

[pool domain.tld] server reached max_children setting (100), consider raising it

There is error for [pool domain.tld] a setting of "100" and in GUI "20". The system said "100", so it should be "100" in Plesk.

I dont added a custom php.ini in /conf. This php.ini-files are 2-3 years old and from root. Maybe technical service have make somthing wrong in the past.

Again.
/opt/plesk/php/7.3/etc/php-fpm.d/domain.tld says 100
Plesk GUI for domain.tld says 20.

ok did some tests, as long as I change the settings in the gui for the domain and apply the settings, the gui & domain.tld.conf will match / show same figures. If the domain.tld.conf was modified manualy it seems the gui does not read this settings back from it, perhaps plesk has it saved / cached somewhere else...

So just change the settings via gui and apply should work as expected

Sorry for late answer.

Thats not working for me. I have set in GUI to value 150, but in php.ini its still value of 100.

[php-fpm-pool-settings]
pm.max_children = 100

and "php.ini" is not changed since 2017. Owner/Group of this file is "root" 0644. All other files in this folder are from 2020.
