We allocate enough memory to opcache so that all customers php scripts is cached in opcache. The problem is that our shared hosting customers is able to upload a php script with the following code to empty opcache for ALL customers on that same server: <?php opcache_reset(); Further there is nothing stopping any customers from doing this as frequently as they like. It is a big problem that one single customer can empty the entire opcache for all other customers on the same server. Please add a new .ini function to disable the php code opcache_reset(); from being able to execute, so that we can disable this completely in opcache.ini/php.ini - We do not need to empty opcache by using this PHP code. opcache is emptied when we reload php-fpm, and that is enough for us. The new .ini function should be added to this page: http://php.net/manual/en/opcache.configuration.php - Suggestion for naming of the .ini function: opcache.disable.reset= 0 or 1 Please appreciate that it is problematic for shared hosting providers that any users on a server can run opcache_reset(); in a php script to empty opcache for all other customers on the same server. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77413&edit=1
