Depending on the version you're using, you will see a property FailoverOnNodeLeave on -persistence-service.xml (MessaingPostOfficeService MBean). The default behavior is to only failover if a real crash happens (for instance kill -9). On older versions we only supported failover on crashes and we recently added that "feature" as per users' requests.
