[users@httpd] MaxRequestsPerChild limit is never reached
Hi! I have a little doubt.
I've setup MaxRequestsPerChild to 10000. But when I check how many
requests a child served, it never gets to that number, intstead seems
to die earlier. Is there some kind of 'idle time' or something?
I've looked into the prefork.c and it was too big for me. Any suggestions?

(Saving Eric some typing maybe)
(The following is all by the way in the on-line docs, see
http://httpd.apache.org/docs/2.2/mod/directives.html
> StartServers 150
At start, Apache will start 150 children.
After a while, if they have nothing to do, Apache will start killing off
some, in function of :
> MinSpareServers 5
It will always leave at least 5 living ones, even if they have nothing
to do. Just so that if a few requests come in suddenly, it has a few
children ready to server these requests.
> MaxSpareServers 20
As more requests come in, Apache will start more children, to nhandle
the increased present and future load.
But it will never leave more than 20 children doing nothing.
> ServerLimit 250
That is the absolute maximum number of children it will ever start. But
read the doc at
http://httpd.apache.org/docs/2.2/mod/mpm_common.html#serverlimit
> MaxClients 200
That is the maximum number of requests that will be processed at any one
time. It slimit is ServerLimit.
But again, read the doc above.
> MaxRequestsPerChild 10000
Independently of the above, any child that has handled 10000 requests
already, will die. But it could have been killed before by virtue of
one of the directives above.
