Edit report at https://bugs.php.net/bug.php?id=62726&edit=1 ID: 62726 Updated by: fat@php.net Reported by: olemarkus@php.net Summary: FPM fails to spawn when max_children is set to a high number -Status: Open +Status: Feedback Type: Bug Package: FPM related Operating System: Gentoo Linux PHP Version: 5.4.5 Block user comment: N Private report: N New Comment: Please try using this snapshot: http://snaps.php.net/php5.4-latest.tar.gz For Windows: http://windows.php.net/snapshots/ Previous Comments: ------------------------------------------------------------------------ [2012-08-05 12:16:54] wer at wereveal dot com Discovered that I am experiencing the same problem with PHP 5.3.15 on Gentoo. php- fpm refuses to start correctly. It hangs although the child processes are started and continue to work even after kill -9 on the main command /usr/lib/php5.3/bin/php-fpm -y /etc/php/fpm-php5.3/php-fpm.conf -g /var/run/php- fpm-php5.3.pid Changing the pm.max_children did not seem to fix this for me and I am using pm = dynamic. Works fine with PHP 5.3.14 ------------------------------------------------------------------------ [2012-08-02 12:07:43] olemarkus@php.net Description: ------------ With the following parameters set in php-fpm.conf, FPM refuse to start properly. The worker threads are spawned, but hangs and only a kill -9 will stop them. Setting pm.max_children to a lower number works. The exact config works with PHP 5.4.4. pm = static pm.max_children = 500 Some additional information can be found in downstream bug https://bugs.gentoo.org/show_bug.cgi?id=428194 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62726&edit=1
