A pool size of 1 for a thread count of 20 per process is somewhat
strange. But OK, you could insist on this wish. Yes, it should be
configurable like that.
Start apache with JkLogLevel debug and check the log file about messages
concerning the pool size. You don't need to produce any traffic for
these messages.

Hi,
I have some Application Servers (tomcat) and 1 web server (httpd apache).
(Linux RedHtat 3)
Apache works with the worker mpm.
There is an Apache Tomcat connector to link the web server to the ASs.
I'm trying to limit the number of connection from the web server to the ASs, using the
worker.properties item "connection_pool_size".
For example, I set the following properties in the httpd.conf :
<IfModule worker.c>
ServerLimit 20
StartServers 20
MaxClients 400
MinSpareThreads 40
MaxSpareThreads 100
ThreadsPerChild 20
MaxRequestsPerChild 0
</IfModule>
And set, in the workers.properties of the web server, for all the ASs :
worker.<server_name>.connection_pool_size=1
So, there should be at the maximum, 20 connections (20 worker.httpd process *
connection_pool_size = 20) from the apache web server to each AS, but in fact,
I saw up to 30 connections from the web server to each AS.
Did I understand well how it works ? Why does the "connection_pool_size"
doesn't work ?
Thanks,
Benoit.
