[users@httpd] Apache starting with more child processes thatn startservers directive
Hi All,
I am using Apache version 2.0.55(with prefork) on Linux with three different
httpd.conf files running on 3 different ports and i just loading httpd
multiple times with one config file for each port.
The problem is *:* when i start the apache, it is starting with 3 times more
child processes than the StartServers directive. i.e., if i keep
StartServers as 5 , it is starting with 15 child processes(servers).
what would be the problem for this behaviour?? (even though the apache
starts with more serevrs, it is working fne)
Thanks

Hi Joshua,
I checked the server with server-status and it is showing only 5 child
processes, but at the same time on the server box it is showing 15
processes(with ps -ef).
By analyzing, i came to a conclusion that ....
1. In the server status page it is only showing child processes, which have
their parent id is same as of root process id, like shown below
USER PID PPID
www 13870 0
www 13873 13870
www 13876 13870
www 13877 13870
www 13879 13870
www 13899 13870
2.on the server, it is showing 15 child processes(each child creating one or
more child processes and randomly) on the start up and with in a 2 minutes
the child processes are increasing to 48, even though server serving for
only one request(server-status page). All the child processes are staying
alive till i stop the server.
Thanks,
Sharath

Try firing up mod_status's server-status handler and see what the
processes are doing.

Hi joshua,
i am just starting one instance only, even then it is showing 3*StartServers
processes and one parent process running. if i starts 3 instances, it is
showing 3*StartServers for every idividual instance.
here is my directory structure....
build: /opt/apache2 --> here is goes all the stuf including ...
bin, build, cgi-bin, conf.example, error, htdocs, icons, include, lib, logs,
Makefile, man, manual, modules
(installation)server root: /opt/web/apache --> here .....
bin, cgi-bin, conf(httpd1.conf, httpd2.conf, httpd3.conf), docroot, log,
modules, run, scripts, ssl
i wrote a script which calls the httpd multiple times with one config file
for each port
(script goes like ...... /opt/apache2/bin/apachectl -f
/opt/web/apache/conf/httpd1.conf -k start,
and ..... httpd2.conf -k start..... httpd3.conf -k start) , and it just
seems to be working.
Thanks,
Sharath

Well, there are still lots of details missing in this question. If
you are starting 3 instances of apache, you should expect
3*StartServers processes to be running. The three instances will be
entirely independent. If that is not what you are seeing, you need to
be more specific about your problem.
