Tomcat configuration

Hey folks, I asked this question on the Tomcat list, but I'll ask it here as
well in case anyone has had experience with this...

Can someone offer some suggestions on configuring the number of connections
Tomcat 4.1 will accept? I am using a stress tester to access the sample
servlet (http://localhost:8080/examples/servlet/HelloWorldExample).
Somewhere around 14-15 concurrent requests, I start seeing
"java.net.ConnectException: Connection refused: connect"

Looking in the Tomcat server.xml file, I see

    <Connector className="org.apache.coyote.tomcat4.CoyoteConnector"
               port="8080" minProcessors="5" maxProcessors="75"
               enableLookups="true" redirectPort="8443"
               acceptCount="10" debug="0" connectionTimeout="20000"
               useURIValidationHack="false" />

I assume this is the connector I'm going through (since my URL is referring
to port 8080). According to the docs
(http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/webapp.html)
acceptCount and maxProcessors should affect this behavior, but I am not
seeing any changes when I adjust them upwards. Should I be looking
elsewhere? Anyone have any suggestions?

Thanks,
Christian
