Bug #73183 [Opn]: Segfaults / zend_mm_heap corrupted

Edit report at https://bugs.php.net/bug.php?id=73183&edit=1 ID: 73183 Updated by: laruence@php.net Reported by: schnederle at futureweb dot at Summary: Segfaults / zend_mm_heap corrupted Status: Open Type: Bug Package: Reproducible crash Operating System: Centos 7.2.1511 PHP Version: 7.0.11 Block user comment: N Private report: N New Comment: you may try to set opcache.protect_memory=1 (please note this will significantly slowdown the server). and see if there is any unexpected write to shared memory Previous Comments: ------------------------------------------------------------------------ [2016-09-27 12:13:10] schnederle at futureweb dot at Description: ------------ Hello, since we switched from PHP 5.3 to PHP 7.0.x (tried multiple Versions of PHP 7 - now we are on 7.0.11) we get random segfaults / zend_mm_heap corrupted with our CMS. Unfortunately not predictable when they will occur or on which Script. (unfortunately never the same) Sometimes a few Days no problems - sometimes 5 times a Day ... Not 100% sure - but I believe that opcache could be the cause of the Problem - as a simple "opcache_reset();" is enough to get everything up & running again - no complete restart of Apache needed. Error Log / Backtrace: http://temp.in.futureweb.at/php/error.log Hope someone can help me on this ... Thank you Andreas Schnederle-Wagner ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73183&edit=1
