How apache keeps track of them and how it get's out of sync?
Now....thing are really weird. I've restarted apache and apache comes up
and total_processors is allready = 10 and idle = 3. If i made first
requests to apache.

Now remember a while ago ( SUBJECT: [peruser] Segmentation fault DATE:
06.08.2006) I had connections segfaulting. I got a patch from you that
should close the broken connection without making apache to segfault.
After the patch I got "Bad file descriptor: apr_socket_opt_set:
(TCP_NODELAY)" error on apache log so I modified it to return instead
of continue.
Is this OKay doing? I've added the patch.

Hi,
can you try to find messages of the following format in your logs?
CHECKING IF WE SHOULD CLONE A CHILD...
total_processors = %d, max_processors = %d
idle_processors = %d, min_free_processors = %d
Startup of new children is based on these values. Wither these values
get incorrect over time (e.g. the server still thinks that he has free
idle processors when he in fact doesn't) or this section is never called
(in which case these messages won't appear at all).
(This problem is another argument for having a handler to display the
contents of the child_info_table. I'll try to find some free time in
order to code one).
