Summary: User Session handler Crash [FPM and APC]
Status: Open
Type: Bug
Package: Session related
Operating System: Debian Lenny Linux
PHP Version: 5.3.3
Block user comment: N
New Comment:
Those are processes, not threads. There is a root-owned master process
that
preforks multiple child processes to handle requests. Simple set that
to a low
number in your config file and attach gdb to one of the children. It's
easy.

ive tried that but it doesnt propagate to child processes and php-fpm is
multy threaded.

Just attach gdb to a runnning php-fpm process.
gdb /usr/bin/php-fpm 1234
where 1234 is the process id. Then hit 'c' for continue in gdb and hit
port 80
until you hit the process you attached to.

its not that easy for php-fpm, and this is php-fpm specific.
