Description

According to the javadoc, ServiceUnavailableException is thrown when attempting to communicate with a directory or naming service and that service is not available. It might be unavailable for different reasons. For example, the server might be too busy to service the request, or the server might not be registered to service any requests, etc.

We should retry on it.
