My configuration is following: opcache.enable=1 opcache.revalidate_freq=2 opcache.validate_timestamps=1 opcache.log_verbosity_level=4 When accessing test script twice, memory leaks detected. I think this bug occurs when updating cache. This leaks occurs on PHP 5.5(Git-2015-05-08), PHP 5.6(Git-2015-05-08). But it does not occur on PHP 7.0(Git-2015-05-08) Test script: --------------- <?php touch(__FILE__); sleep(3); Expected result: ---------------- Memory does not leak. vagrant@php7dev:/var/www/default$ sudo tailf /var/log/nginx/php-fpm_error.log [08-May-2015 01:03:13] NOTICE: fpm is running, pid 25975 [08-May-2015 01:03:13] NOTICE: ready to handle connections [08-May-2015 01:03:17] WARNING: [pool www] child 25978 said into stderr: "Fri May 8 01:03:17 2015 (25978): Message Cached script '/var/www/default/test/opcache_touch_self.php'" [08-May-2015 01:03:22] WARNING: [pool www] child 25976 said into stderr: "Fri May 8 01:03:22 2015 (25976): Message Cached script '/var/www/default/test/opcache_touch_self.php'" Actual result: -------------- Memory leaks. vagrant@php7dev:/var/www/default$ sudo tailf /var/log/nginx/php-fpm_error.log [08-May-2015 01:03:13] NOTICE: fpm is running, pid 25975 [08-May-2015 01:03:13] NOTICE: ready to handle connections [08-May-2015 01:03:17] WARNING: [pool www] child 25978 said into stderr: "Fri May 8 01:03:17 2015 (25978): Message Cached script '/var/www/default/test/opcache_touch_self.php'" [08-May-2015 01:03:22] WARNING: [pool www] child 25976 said into stderr: "Fri May 8 01:03:22 2015 (25976): Message Cached script '/var/www/default/test/opcache_touch_self.php'" [08-May-2015 01:03:25] WARNING: [pool www] child 25976 said into stderr: "[Fri May 8 01:03:25 2015] Script: '-'" [08-May-2015 01:03:25] WARNING: [pool www] child 25976 said into stderr: "/home/vagrant/php-src/ext/opcache/ZendAccelerator.c(1931) : Freeing 0x7F62A4877CF0 (45 bytes), script=-" [08-May-2015 01:03:25] WARNING: [pool www] child 25976 said into stderr: "=== Total 1 memory leaks detected ===" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69598&edit=1
