This call results in three events every time. We are also running the receiver which is continuously listing to those events from the topic. Problem: When i terminate one of my JBoss node in cluster, client pauses for few seconds and then resumes events from other node. But, some events are missed during this process. plz. suggest View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4250894#...
