Bug #75579 [Opn]: All Interned Strings Free memory used and PHP crashes

Edit report at https://bugs.php.net/bug.php?id=75579&edit=1 ID: 75579 User updated by: post at minhost dot no Reported by: post at minhost dot no Summary: All Interned Strings Free memory used and PHP crashes Status: Open Type: Bug Package: opcache Operating System: CentOS 7.4 PHP Version: 7.1.12 Block user comment: N Private report: N New Comment: I just now today installed the latest 7.1 development branch from here https://github.com/php/php-src/branches and tested it. I am sorry to see the problem is still not solved with any of the patches that have been made so far. PHP still crashes for me after visiting a few WordPress sites. This time it seemed to happen right after opcache got a automatic OOM restart.

After more testing on PHP 7.1.12 with the patch from bug #75573 applied: http://git.php.net/?p=php-src.git;a=commit;h=3b9ba7b6bd9e24bdbeca8e8e3f24cee2fccc51d8 - still the bug is present! After visiting about nine wordpress sites on the test server, the interned strings used memory became full and PHP sites started to crash and go down. From apache error log for one of the domains after it stopped working: [Thu Nov 30 15:40:40.273796 2017] [proxy_fcgi:error] [pid 17990:tid 140238684755712] [client 176.74.214.18:42343] AH01071: Got error 'PHP message: PHP Fatal error: Cannot declare interface JsonSerializable, because the name is already in use in /home/USER/domains/DOMAIN.TLD/public_html/wp-includes/compat.php on line 428\n' [Thu Nov 30 15:40:41.697018 2017] [proxy_fcgi:error] [pid 17990:tid 140238693148416] [client 176.74.214.18:52760] AH01071: Got error 'PHP message: PHP Fatal error: Cannot declare interface JsonSerializable, because the name is already in use in /home/USER/domains/DOMAIN.TLD/public_html/wp-includes/compat.php on line 428\n' So this still prevents us from upgrading to PHP 7.1.12. Remeber the bug is not present in PHP 7.1.11 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
