Apache 2.0.49 error

Hello together!

I have a very interesting problem on my webserver, a Suse Linux 9.1
with Apache 2.0.49:
After running a few hours the memory usage of the httpd2-prefork slows
down the whole system, not only web-sites.
when I put a ps aux | grep apache I get:

You see that there are very many processes, getting more. When I kill
all except for one the system is nearly idle, but web-sites don´t open
fully and open extremely slow.

Does anybody know what this could be???

thanks,
petra

Those are not processes, they are children, they share memory and
other resources, even if they appears like different processes.

Evidently you have a lot of connections or you are using some kind of
server-programmin (php? SSI?) that require a lot of resources, if you have
enabled server-status (and if you didn't, it's a good moment to do so),
try to check the status of the server.

Hmmm, I searched the web myself and found out that these "children"
are not the problem if they are closed or killed automatically after a
timeout time. This is my problem, somtimes this doesnt happen and
these "children" use CPU an MEM.

I tried to enable Apache2 with mod_status, but it is not working.
I did all the things mentioned in
http://httpd.apache.org/docs-2.0/de/mod/mod_status.html

but it doesn´t work. When I rund apachectl2 status I get a 404 error,
also in Lnyx.

So what could be reason why server-status does not work.

My httpd.conf says:
Include /etc/apache2/mod_status.conf
this file says:
<Location /server-status>
SetHandler server-status

Order Deny,Allow
Deny from all
Allow from .foo.com
</Location>

is this enough or to I have to compile something ???

Thanx a lot

How about http://httpd.apache.org/docs-2.0/mod...html#rlimitcpu ?
Note: limiting CPUtime to 5 minutes, still may keep a child alive for manu
wallclock hours: time spend waiting for data-base response is not accounted.

Peeking around in the source, it seems apachectl tries to view
http://localhost:80/server-status via lynx. Installation may change the
portnumber before compiling; cann't find an option to change either port or
link at runtime. (/support/apachectl.in)
This is likely to fail if you do not listen to _all_ IP or changed the port
of your default host after first time install-and-compile.

Access is only _allowed_from_ the domain .foo.com ... guess that's not your
domainname ;-)

Have included this in server-tuning.conf, hope it works!

in listen.conf activated port is 80

Sorry, my fault, copied it here from the apache-website, my
mod_status.conf says localhost

So any idea why I get the 404 error ???
