<many more only dots lines follow>
Based on the Lines x DotsPerLine, I have 8192 slots.
Is that a correct interpretation? How do I reconcile this against
my MPM config of MaxClients = 2048?
<IfModule mpm_worker_module>
ServerLimit 64
StartServers 32
MaxClients 2048
MinSpareThreads 25
MaxSpareThreads 100
ThreadsPerChild 32
MaxRequestsPerChild 0
</IfModule>
I know only 32 slots/line are filled due to ThreadsPerChild.
These are beefy Nehalems, should I consider upping ThreadsPerChild?
Also, I'm seeing httpd processes created and destroyed (in top)
more frequently than I would expect. Is there something awry in
the config that would cause this to be so?
Finally, this httpd is a front end for a Tomcat instance, via mod_proxy_ajp.
Does this fact weigh on any configuration decisions (other than ensuring TC
can
Handle the same MaxClients?
Thank you for any pointers,
David
