JBMessaging cluster stops working after a node gets suspended (kill -STOP) and unsuspended (kill -CONT) after few minutes ------------------------------------------------------------------------------------------------------------------------- Key: JBMESSAGING-1902 URL: https://issues.jboss.org/browse/JBMESSAGING-1902 Project: JBoss Messaging Issue Type: Feature Request Components: JMS Clustering Affects Versions: 1.4.8.SP3 Environment: JBoss EAP 5.1.0 Reporter: Tom Ross Assignee: Yong Hao Gao Priority: Blocker This is a very simple cases where two node JBoss Messaging cluster stops working after one node gets suspended (kill -STOP) for few minutes. It would appear that when the node wakes up from the suspension it misses jgroups notifications and carries on as if nothing ever happened. Meantime while the node was suspended the remaining node performed failover and deleted the suspended node from the jbm_cluster table. How to reproduce the problem. Create a two node cluster using all profile. start node 1 start node 2 after both nodes are running find out pid of the JVM hosting node 2 and pid of the shell process ps -fu ${user-name} | grep java kill -STOP pid-jvm kill -STOP shell running jvm wait 5 minutes kill -CONT shell running jvm kill -CONT pid-jvm Observe that node 1 has noticed that node 2 is missing and performed failover node 2 has been remved from JBM_CLUSTER table. JGroups is functioning normally JBM cluster is not working node 2 is not part of the cluster any longer.
