Are you sure? It isn't impossible that you are using the APR/Native
connector given your configuration but it would be unusual.
Look in the logs for a line that contains:
org.apache.coyote.AbstractProtocol.start Starting ProtocolHandler ...
What is the full text of that line?
Also, what version of the Tomcat Native Connector are you using?
Look in the logs for a line that contains:
org.apache.catalina.core.AprLifecycleListener.lifecycleEvent Loaded
Apache Tomcat Native library [???] using APR version [???]
What is the full text of that line?

I ran some simple tests with ab and I cannot repeat the problem you
describe.
As I increase the concurrency with ab, currentThreadCount increases.
I even reduced minSpareThreads to 0 and I still could not reproduce the
behaviour.
To investigate this further you'll need to provide the steps to
reproduce this from a clean install of the latest stable 9.0.x release
(9.0.38 as I type this) and the latest stable Tomcat Native (1.2.25).
Ideally the test case would involve nothing more than a clean Tomcat
install and ab to generate the load.
