New Comment:
Thanks for your answers.
@mplomer : Yes, I said it in my first post, dynamic & static modes are still
working perfectly.
But I did not set the catch_something_** = yes, and it seems its default value
is "no" so this is probably why it was not working.
I am going to install the V10 patch and I'll tell you so.

Here is the v10 of the patch. It corrects the bug trollofdarkness and dbetz
have
found.
In fact the array which is storing event has not been sized up and the event
was
not added. It was working when settings catch_workers_output to yes (but breaks
this feature).
This should now be OK.
test and report please.

@Troll: Does FPM works for you, when using the "dynamic" or "static" pm? Seems
more like an error in the Apache setup, which is somewhat tricky.

To sum up the patch:
1- new configuration:
* in globals: events.delay (default 500µs). It's the delay between 2 triggers
on a FD event. You can disable the delay by setting it to 0. You should change
it when the ondemand PM
forks more child than it should do.
* in pools: pm = "ondemand" to active the ondemand PM. In this mode, no
processes are forked at startup but when requests are comming
* in pools: pm.process_idle_timeout the time a process should stay idle
without serving any requests before it's killed
2- Here is the debug log I have when setting log_level to debug, error_log to
/dev/stderr and daemonize to no:
