Hi

I have problem I don't know how to solve. Sometimes the JMS client take to long 
to failover and throw an exception on the client, this is not consistent but 
something we can reproduce 6-10 times.
The servers is not stressed at all and the same goes for the client.
 

- 2 JBoss 5.1 servers running in a cluster
- 2 clients connect to a topic queue
- Messaging client 1.4.7.GA
- remoting 2.5.1

1) if I use the default values "remote-sslbisocket-service.xml" our client 
thinks it's should failover on startup. This fail with an JMSException and In 
this case we reconnect to the topic and after this every thing works fine. if I 
bring down one of the servers, it fail over as expected. But because it fail on 
startup there is possibility we miss messages because it use a minute to 
discover the failover didn't work  


2) if I change the values validatorPingTimeout to 10000 and validatorPingPeriod 
= 15000 we are able to start our client with out the JMS client thinks it 
should failover and messages are received. But if I bring down one of the two 
servers it fail in the failover procedure with an JMSExeception
