So what's your problem?  Are you using Linux?  Did you know that Linux shows
threads as processes using "ps"?  Are you running out of memory?  A little
more information would be helpful.

looking the internet, the solution is use the -Xmx , -Xms and use the className="org.apache.tomcat.service.PoolTcpConnector" and i'm working with Ajp13

 <Connector className="org.apache.tomcat.service.PoolTcpConnector"> <Parameter name="handler" value="org.apache.tomcat.service.connector.Ajp12ConnectionHandler"/> <Parameter name="port" value="8007"/> <Parameter name="max_threads" value="30"/> <Parameter name="max_spare_threads" value="20"/> <Parameter name="min_spare_threads" value="5" /> </Connector>
Thanks
Fabian
