Hello Morten,
Thank you for reaching out! In the dock you followed it states:
"For cPanel servers, CageFS version 6.0-42 or higher performs cleaning of PHP sessions based on
session.gc_maxlifetime and
session.save_path directives specified in proper
php.ini files."
In this case, you need to check which version of Cagefs you have on the server, if 6.0-42 or higher, then you need to check the value of the
session.save_path variable
in
/opt/alt/php74/etc/php.ini - maybe it is not equal to
/opt/alt/php74/var/lib/php/session, so those session files were not cleaned by the crown.
It would be better if you create a ticket here

Thank you for contacting us.
