The PHP Version 5.3.15 / 5.3.16 and current Git branch PHP 5.3 is affected. /usr/sbin/php5-fpm --fpm-config /etc/php5/fpm/php-fpm.conf All pools are started and working, but the php5-fpm does not detach: /usr/sbin/php5-fpm --fpm-config /etc/php5/fpm/php-fpm.conf and here it hangs. ctrl +c does not work. strace tells me: Process 15949 attached - interrupt to quit futex(0x7fb923e8ce40, FUTEX_WAIT_PRIVATE, 2, NULL If I switch the configuration option "daemonize" to "no" php-fpm starts up normal and can be aborted with ctrl+c. If I copy sapi/fpm from 5.3.14 to the current php-src from git and compile it again my configuration and php-fpm works and starts normal. If I remove the USR1/USR2 handling from sapi/fpm/fpm/fpm_unix.c ( see patch ) php-fpm starts normal and detach correctly. I think (See: http://groups.google.com/group/highload-php-en/browse_thread/thread/fa6b16d533411f42) PHP 5.4 branch is also affected.
