> The service records written to the registry are removed by ServiceClient on a
> destroy call, but not on a stop call. The service AM does have some code to
> clean up the registry entries when component instances are stopped, but if
> the AM is killed before it has a chance to perform the cleanup, these entries
> will be left in ZooKeeper. It would be better to clean these up in the stop
> call, so that RegistryDNS does not provide lookups for containers that don't
> exist.
