the relationship between connection_pool_size and tp-processor?

apache2 workers.properties:

worker.node223.connection_pool_size=100
worker.node223.connection_pool_minsize=50

tomcat server.xml:

<Connector address="192.168.0.17" port="8009" maxHttpHeaderSize="64836"
           maxThreads="350" minSpareThreads="50" maxSpareThreads="200"
           acceptCount="700&q开发者_JAVA百科uot; connectionTimeout="360000" disableUploadTimeout="true"
           enableLookups="false" URIEncoding="UTF-8" protocol="AJP/1.3" />

connection_pool_size should mean that max tcp connection numbers should be establish to backend server(tomcat).When I run kill -3 for tomcat server.as following:

........

........

then I get :

there are 295 TP-Processors, I guess 295< connection_pool_size+maxSpareThreads = 300； 295 < maxThreads = 350, it is ok.

there are 189 Tp-processors (In WAITING ) < maxSpareThreads = 200, it is ok.

there are 106 TP-Processors(In RUNNABLE ) > connection_pool_size = 100,I think it is wrong.

am I doing something wrong? And if not, do you know a possible explain to this? thanks

If im reading you right, then 100 is the max threads per worker. Perhaps there is more than one worker running.
