Hi Team, I have deployed an application in JBoss 7.1 and it worked well with minimum request. When we started with multiple action (mass delete of 200 records), getting session expired after 5 minutes and in parallel no users able to login. All the request has been blocked. Below is my configurations. <session-bean> <stateless> <bean-instance-pool-ref pool-name="ptest"/> </stateless> <stateful default-access-timeout="5000" cache-ref="simple"/> <singleton default-access-timeout="5000"/> </session-bean> <mdb> <resource-adapter-ref resource-adapter-name="hornetq-ra"/> <bean-instance-pool-ref pool-name="ptest-strict-max-pool"/> </mdb> <pools> <bean-instance-pools> <strict-max-pool name="slsb-strict-max-pool" max-pool-size="20" instance-acquisition-timeout="5" instance-acquisition-timeout-unit="MINUTES"/> <strict-max-pool name="mdb-strict-max-pool" max-pool-size="20" instance-acquisition-timeout="5" instance-acquisition-timeout-unit="MINUTES"/> <strict-max-pool name="ptest"/> <strict-max-pool name="ptest-strict-max-pool" max-pool-size="200" instance-acquisition-timeout="15" instance-acquisition-timeout-unit="MINUTES"/> </bean-instance-pools> </pools> Thanks and Regards, Boomi _______________________________________________ jboss-as7-dev mailing list jboss-as7-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-as7-dev
