is there a possibility to reload a separate fcgid-application

May be the php.ini for my wrapper-script has changed and i want to
reload this application for vhost without disturbing other apps.
Is this possible? I think a reload of apache stops all
fcgid-applications and force to restart them, is this notice correct?
there are a lot of httpd <defunct> in processlist after reloading apache.
iam afraid of killed apps and a cpu-overload if a lot applications
start at the same time.
I am not very familiar with mod_fcgid, but hat you want is possible with
what I am running:
httpd 2.3.12-dev with mod_proxy_fcgi
PHP 5.3.7-dev with php-fpm
php-fpm runs as a separate service from Apache HTTP Server; it is
started by the system init scripts (just as httpd is). Sending a
SIGUSR2 to php-fpm will cause it to gracefully reload all workers and
re-read its configuration file. While this causes *all* applications
(pools) to be reloaded gracefully (without end users noticing), it
should be possible to set up multiple instances of php-fpm, each with
its own config file, with each instance having one pool with one
application -- you can then send the SIGUSR2 to only the master process
of php-fpm that handles the application you want to have reloaded.
While what I describe above is "bleeding edge" -- and so might be a
longer-term strategy rather than an immediately usable one for most
people -- httpd 2.3 is in beta and a general (non-beta) release of 2.4
seems to be not very far away. Note that php-fpm from PHP 5.3.6 won't
work out of the box with mod_proxy_fcgi, but a fix for this has already
been accepted and will be in PHP 5.3.7 when it is released.
