I was assuming that "worker.c" was the code that spawned the threads.
(remember, this is 2.2.22, not 2.4.0, in case that makes any difference)
So, please correct me where I am wrong:
from "/etc/httpd/extra/httpd-mpm.conf
#
# Only one of the below sections will be relevant on your
# installed httpd. Use "apachectl -l" to find out the
# active mpm.
#
... I assumed that this is where "worker.c" was telling me that mpm=worker
<IfModule mpm_prefork_module>
....
# worker MPM
# StartServers: initial number of server processes to start
# MaxClients: maximum number of simultaneous client connections
# MinSpareThreads: minimum number of worker threads which are kept spare
...
<IfModule mpm_worker_module>
StartServers 2
MaxClients 150
MinSpareThreads 25
...
<IfModule mpm_beos_module>
etc..
Note - these are the ONLY compiled in modules:
root@x105:[/]apachectl -l
Compiled in modules:
core.c
worker.c
http_core.c
mod_so.c

OR
root@x105:[/]apachectl -M

Syntax OK
which is the result of:
./configure --enable-layout=AIX --with-mpm=worker --enable-mods-shared=all
It is what I "expected", so where am I going wrong?
