[users@httpd] about ServerLimit and ThreadLimit
Hello,
On the documentation of Apache2.2
ServerLimit <../mod/mpm_common.html#serverlimit>is a hard limit on the
number of active child processes, and must be greater than or equal to the
MaxClients <../mod/mpm_common.html#maxclients> directive divided by the
ThreadsPerChild <../mod/mpm_common.html# threadsperchild> directive.
ThreadLimit <../mod/mpm_common.html#threadlimit> is a hard limit of the
number of server threads, and must be greater than or equal to the
ThreadsPerChild <../mod/mpm_common.html#threadsperchild> directive.
I did like above on worker MPM but server reached Max connection when 256th
connection come.
<IfModule mpm_worker_module>
StartServers 5
MaxClients 350
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 0
ServerLimit 40
ThreadLimit 40
</IfModule>
Is there something wrong in my configuration ?
Regards,
Tseveen.

I'm afraid I can't drive you, you'll have to read the documentation
about the process models. Here's a good start:-
http://httpd.apache.org/docs/2.2/mpm.html
http://httpd.apache.org/docs/2.2/mod/prefork.html
It might be that switching to the worker MPM is what you want, or you
might want to stay with prefork and just increase MaxClients but
you'll have to read about the MPMs and decide.
After reading the docs, if you have a specific issue you need help
with then feel free to come back with a suitably constructed smart
question and we'll be happy to help.

Cheers,
Phil.

You're right. Thank you very much. Solved

My guess is that you're not using the worker MPM, and that you're
actually using the prefork MPM which is the default. Run a 'apachectl
-l' and see the modules you've got compiled-in. If you see 'prefork.c'
then that's why. See the docs for changing to worker if that's what
you want.
Cheers,
Phil.
