> According to the 
> [javadoc|https://docs.oracle.com/javase/7/docs/api/javax/naming/ServiceUnavailableException.html],
>  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.
