Without loading xcache PHP module everything works also fine for us in 5.3.17. Maybe this is also related to this bug: Bug https://bugs.php.net/bug.php?id=63005.

All of the sudden, it pops without explanation. ------------------------------------------------------------------------ [2012-09-16 01:34:28] admin at yqed dot com The error format I get when I restart the php-fpm service: # service php-fpm restart Stopping php-fpm: [ OK ] Starting php-fpm: /bin/bash: line 1: 20659 Segmentation fault /usr/sbin/php- fpm -y /etc/php-fpm/php-fpm.conf [FAILED] ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
