hello tony , i have the same problem with SLSB. the pooling parameters for SLSB and SFSB is described info jboss configuration file : standardjboss.xml | <container-configuration> | <container-name>Standard Stateless SessionBean</container-name> | <call-logging>false</call-logging> | <invoker-proxy-binding-name>stateless-unified-invoker</invoker-proxy-binding-name> | <container-interceptors> | <interceptor>org.jboss.ejb.plugins.ProxyFactoryFinderInterceptor</interceptor> | <interceptor>org.jboss.ejb.plugins.LogInterceptor</interceptor> | <interceptor>org.jboss.ejb.plugins.SecurityInterceptor</interceptor> | <!-- CMT --> | <interceptor transaction="Container">org.jboss.ejb.plugins.TxInterceptorCMT</interceptor> | <interceptor transaction="Container">org.jboss.ejb.plugins.CallValidationInterceptor</interceptor> | <interceptor transaction="Container">org.jboss.ejb.plugins.StatelessSessionInstanceInterceptor</interceptor> | <!-- BMT --> | <interceptor transaction="Bean">org.jboss.ejb.plugins.StatelessSessionInstanceInterceptor</interceptor> | <interceptor transaction="Bean">org.jboss.ejb.plugins.TxInterceptorBMT</interceptor> | <interceptor transaction="Bean">org.jboss.ejb.plugins.CallValidationInterceptor</interceptor> | <interceptor>org.jboss.resource.connectionmanager.CachedConnectionInterceptor</interceptor> | </container-interceptors> | <instance-pool>org.jboss.ejb.plugins.StatelessSessionInstancePool</instance-pool> | <instance-cache></instance-cache> | <persistence-manager></persistence-manager> | <container-pool-conf> | <MaximumSize>100</MaximumSize> | </container-pool-conf> | </container-configuration> | here is maximum size of pool - 100 but it does not working correctly, I noticed that the CreateCount continues to increment over time, while RemoveCount is rarely incremented. For example, I may have a CreateCount in the tens-of-thousands while the RemoveCount stays in the hundreds. any idea will be greatly appreciated.
