Bug #53074 [NEW]: Sending php-fpm service a HUP signal causes problems with daemontools

From: Operating system: Linux (funtoo/gentoo) PHP version: 5.3.3 Package: FPM related Bug Type: Bug Bug description:Sending php-fpm service a HUP signal causes problems with daemontools Description: ------------ I'm running php-fpm with DJB daemontools (daemonize = no) process supervisor. Every time I send the process a HUP signal (graceful reload) the process is in some way "detached" from daemontools so it's not possible to reload it because it's already runninng. Since the children processes aren't properly (?) terminated, php-fpm refuses to start: Test script: --------------- # ps axf 1806 ? Ss 0:00 /bin/sh /command/svscanboot 1809 ?
