Every Website has his own User and PHP-FPM Pool. I tried to activate OPcache securely - because of the Shared Cache Problem - with this settings in every Pool: php_admin_value[opcache.enable] = 1 php_admin_value[opcache.enable_cli] = 0 php_admin_value[opcache.memory_consumption] = 256 php_admin_value[opcache.max_accelerated_files] = 32531 php_admin_value[opcache.validate_timestamps] = 1 php_admin_value[opcache.revalidate_freq] = 0 ;php_admin_value[opcache.fast_shutdown] = 0 php_admin_value[opcache.file_cache] = /home/website1/opcache php_admin_value[opcache.file_cache_only] = 1 php_admin_value[opcache.validate_permission] = 1 Every Pool has his own settings for file-cache. I understand these settings that there is no shared memory... only the file-cache with 256 MB for every website. But it didnt work as expected. NGINX has many SEGFAULTS with PHP7.4 in error.log. When i deactivate OPcache all is working fine. With PHP7.3 i never get these SEGFAULTS. Maybe there is a Bug in PHP or Configs are wrong - i really dont know. I hope you can help me or show me a working solution. THX Test script: --------------- I dont have. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=80864&edit=1
