[jboss-jira] [JBoss JIRA] Updated: (JBMESSAGING-1842) Live node dropping out of cluster can cause duplicate message delivery

Live node dropping out of cluster can cause duplicate message delivery ---------------------------------------------------------------------- Key: JBMESSAGING-1842 URL: https://issues.jboss.org/browse/JBMESSAGING-1842 Project: JBoss Messaging Issue Type: Bug Components: JMS Clustering Affects Versions: 1.4.0.SP3.CP10, 1.4.0.SP3.CP11, 1.4.7.GA Reporter: Justin Bertram Assignee: Yong Hao Gao Fix For: 1.4.0.SP3.CP12, 1.4.8.GA When a live node is kicked out of the cluster (for whatever reason) its JBoss Messaging ServerPeer remains active which means the node is still available to send messages to clients. However, when the node is kicked out of the cluster another node in the cluster performs fail-over for that node and takes ownership of that node's messages in the database. The "dead" node may know nothing about this and might believe it still owns those messages and therefore will deliver those messages to clients. After delivery it tries to remove the message from the database and can't (because it doesn't actually own that message anymore). When this happens the "dead" node issues a WARN like this: WARN [JDBCPersistenceManager] Failed to remove row for: Reference[23318958991900672]:RELIABLE Of course, the node which performed the fail-over and actually owns the message now may also deliver the message to a client.
