Hi Justin, You're in the right forum - the ServerThread you're looking at is an org.jboss.remoting.transport.socket.ServerThread, and the pool of ServerThreads is configured in the org.jboss.remoting.transport.socket.SocketServerInvoker that services EJB3s. The configuration is found in file $JBOSS_HOME/server/$CONFIG/deploy/ejb3.deployer/META-INF/jboss-service.xml, in particular, the lines | <mbean code="org.jboss.remoting.transport.Connector" | name="jboss.remoting:type=Connector,name=DefaultEjb3Connector,handler=ejb3"> | <depends>jboss.aop:service=AspectDeployer</depends> | <attribute name="InvokerLocator">socket://${jboss.bind.address}:3873</attribute> | <attribute name="Configuration"> | <handlers> | <handler subsystem="AOP">org.jboss.aspects.remoting.AOPRemotingInvocationHandler</handler> | </handlers> | </attribute> | </mbean> | If, for example, you want to increase the number of worker threads, append the "maxPoolSize" parameter to the InvokerLocator attribute: | <attribute name="InvokerLocator">socket://${jboss.bind.address}:3873/?maxPoolSize=500</attribute> | For more information, see the Remoting Guide (http://www.jboss.org/jbossremoting/docs/guide/2.2/html/index.html), particularly Section 5.4.5. "Socket Invoker". -Ron View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4180149#...
