To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes.

Thank you for helping us make PHP better. I can not reproduce this. ------------------------------------------------------------------------ [2016-03-14 12:51:01] contact at sshilko dot com It's Amazon AWS EC2 instance ami-b82176d2 as a base (Ubuntu 14.04.03 LTS) ubuntu/images/ebs/ubuntu-trusty-14.04-amd64-server-20151218 - ami-b82176d2 ------------------------------------------------------------------------ [2016-03-14 12:41:20] contact at sshilko dot com This is a clean system i'm installing via puppet/vagrant script. Only change i have is PHP version, i updated from 5.5 to 5.6 to 7.0.1-5+deb.sury.org~trusty+1 to 7.0.2-2+deb.sury.org~trusty+1 and now tried 7.0.4-5+deb.sury.org~trusty+1 but it failed immediattely due to log_level, after uncommenting it works. modules & info https://gist.github.com/sshilko/5dce14eccd90f43dea33 ------------------------------------------------------------------------ [2016-03-14 12:28:55] ondrej@php.net Sergei, what other modules do you have installed? Could you perhaps attach output of: php -r 'phpinfo();' I can't reproduce it with just php-fpm and neither with basic set of modules installed nor with full php7.0-* set of external modules as provided in the PPA. Re-running under valgrind also doesn't reveal anything suspicious. Correctly ends with: ``` [14-Mar-2016 12:26:22] ERROR: [/etc/php/7.0/fpm/php-fpm.conf:415] unknown entry 'log_level' [14-Mar-2016 12:26:22] ERROR: failed to load configuration file '/etc/php/7.0/fpm/php-fpm.conf' [14-Mar-2016 12:26:22] ERROR: FPM initialization failed [Inferior 1 (process 74801) exited with code 0116] ``` Any PECL modules (php-* packages)? Or anything under /usr/local? What does ldd /usr/sbin/php-fpm7.0 output? Can you reproduce this on clean system? (And if not, what's the difference between the two systems?) ------------------------------------------------------------------------ [2016-03-14 12:13:26] ondrej@php.net And that said script is just a simple wrapper around php-fpm -t: $ cat debian/php-fpm-checkconf #!/bin/sh set -e CONFFILE=${1:-/etc/php/@PHP_VERSION@/fpm/php-fpm.conf} errors=$(/usr/sbin/php-fpm@PHP_VERSION@ --fpm-config "$CONFFILE" -t 2>&1 | grep "\[ERROR\]" || true); if [ -n "$errors" ]; then echo "Please fix your configuration file..." echo $errors exit 1 fi exit 0 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
