In a load balanced OSB cluster, the 2nd node fails to connect to the Aggregator.

The servers in the cluster are using certificates which match the load balancer names, but the "ALSB Statistics manager" is attempting to connect over t3s directly to the first node.

The OSB cluster has the "Http Frontend Host" value set to the load balancer's name.

You may see an error similar to this one in the log files:

<Jun 24, 2010 3:01:00 PM EDT> <Error> <ALSB Statistics Manager> <BEA-473003> <Aggregation Server Not Available. Failed to get remote aggregator

Certificate contained "loadbalancer-hostname" but check expected "aggregator-hostname"; No available router to destination]
