Summary: Sending php-fpm service a HUP signal causes problems
with daemontools
Status: Closed
Type: Bug
Package: FPM related
Operating System: Linux (funtoo/gentoo)
PHP Version: 5.3.3

Hello fat,
I forgot to run the patch at that time and since it has been incorporated to
the core, I thought it would be good to send the information again.
Tested using PHP version 5.3.8.
Output has been shortened for the sake of brevity.
See PIDs 4645 to 4649 in the php-fpm-address.log file
See PIDs 4942 to 4946 in the php-fpm-address.log file.
When binding to address:port it doesn't start again.
When binding to a socket it starts again but previous childs are detached from
the master process.

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:
