Hi, we are using JBoss 4.0.5.GA (from jems-installer-1.2.0.CR1.jar in the ejb3-cluster configuration). Our application contains a SFSB. After the application is deployed and used in a 2-node cluster) for about 10 minutes, we see these messages in the server.log even when the system is idle: 2006-11-30 17:12:13,947 ERROR [STDERR]
