We are not able to configure the Attributes: <attribute name="FullSize">75000</attribute> | <attribute name="PageSize">2000</attribute> | <attribute name="DownCacheSize">2000</attribute> because of following exception: ObjectName: jboss.mq.destination:name=rawEventTopic,service=Topic | State: FAILED | Reason: org.jboss.deployment.DeploymentException: No Attribute found with name: FullSize | I Depend On: | jboss.mq:service=DestinationManager | jboss.mq:service=SecurityManager | Depends On Me: | HFNSI.bi:name=HFNSIEventBridgeService,type=HFNSIEventBridgeService | Is there any way to avoid the growing Heap Usage and the OutOfMemory?
