Very often it gets a segfault and is blocking the whole php processing, so no answer is serve to the client. For me the backtrace is looking like a infinite loop, but i don't see if it is cause by a script or an internal php module. Is there any chance to see which script/module is involved? The Segfault is always looking like that (dmesg output): php5-fpm[1858]: segfault at 7fffa4de4fa0 ip 0000000000691515 sp 00007fffa4de4f90 error 6 in php5-fpm[400000+800000] PHP Version: php -v PHP 5.5.9-1ubuntu4.11 (cli) (built: Jul 2 2015 15:23:08) Copyright (c) 1997-2014 The PHP Group Zend Engine v2.5.0, Copyright (c) 1998-2014 Zend Technologies with Zend OPcache v7.0.3, Copyright (c) 1999-2014, by Zend Technologies Backtrace of Coredump: (gdb) bt #0 0x0000000000691515 in ??

December 20, 2015 1.5k views LEMP PHP Ubuntu http://stackoverflow.com/questions/32167132/php-fpm-segfault-error-6 A couple of days ago, my OSSEC daemon started sending me syslogs about a segfault in my php5-fpm.
