If you use the log or PID directives for a php-fpm setup it will after a SUSE 15 SP4 upgrade. They included a apparmor profile for php that prevents you from using these directives.
You have 2 choices:
- don’t use the directives or
- disable the apparmor php profile. which will allow you to use them again.
Three was no php apparmor profile before suse15 sp4.
