Hello, I am using JBoss 4.3.0.GA_CP01. I purchased the JBoss Developer Studio and so I got no support contract. I have set up a cluster with 2 Servers and a client which is connected to one of these (Topic with clustered=true and ClusteredConnectionFactory). When I shut down the server to which the client is conected failover is not working and I get the following exception on the client: [java] ERROR 13-10 18:01:46,553 (FailoverCommandCenter.java:failureDetected:186) -Failover failed [java] javax.jms.JMSException: Cannot find a cached connection factory delegate for node -1 [java] at
