I think this is what you meant by php.ini's timeout value:

max_execution_time = 40

Prior to moving to nginx and php-fpm I have never experienced this issue BTW.

Below is a copy of my php-fpm.conf

<?xml version="1.0" ?>

        All relative paths in this config are relative to php's install prefix

                ... in a less than this interval of time, a graceful restart

                Useful to work around accidental curruptions in accelerator's
shared memory.

                                Many BSD-derrived systems allow connections
regardless of permissions.
