Hi Jonatan442;
the STANDARD setting for this option is already
Code:
...
; Defines the probability that the 'garbage collection' process is started
; on every session initialization. The probability is calculated by using
; gc_probability/gc_divisor. Where session.gc_probability is the numerator
; and gc_divisor is the denominator in the equation. Setting this value to 1
; when the session.gc_divisor value is 100 will give you approximately a 1% chance
; the gc will run on any give request.
; Default Value: 1
; Development Value: 1
; Production Value: 1
; http://php.net/session.gc-probability
session.gc_probability = 0
...
So IF you didn't change it manually, I can't remember any software, which modifies this standard setting.
If you still would like to check it, consider either ...
... a usage of:
Code:
find /etc/php -type f -name "*.ini" -exec grep -i -H "session.gc_probability" {} \;
find /etc/php5 -type f -name "*.ini" -exec grep -i -H "session.gc_probability" {} \;
find /opt/plesk/php -type f -name "*.ini" -exec grep -i -H "session.gc_probability" {} \;
find /opt/plesk/php -type f -name "*.ini" -exec grep -i -H "session.gc_probability" {} \;
find /var/www/vhosts/system -type f -name "*.ini" -exec grep -i -H "session.gc_probability" {} \;
As you can see, I use all possible locations in my examples, where php.ini - versions might be located and you will get only an output from the used command, when the search - term "session.gc_probability" exists in files with the ending "ini". It could be a good idea, if you save the command, which can be very easily adjusted to any search - term you desire.
Another hint: If you don't restart your webserver and the depending php-fpm service after you changed PHP - settings, you will still have your old configuration as actual setting!
... or you can browse to:
Home > Tools & Settings > PHP Settings
at your Plesk Control Panel, choose your desired PHP - version and check/modify/adjust at the tab "php.ini" your choosen php.ini.
