> The client is trying to serialize ServerLocation objects and send them to a locator. AutoConnectionSourceImpl.queryOneLocator() has code to handle IOException and report the locator as being down but since ServerLocation isn't a DataSerializableFixedID instance the serialization code throws a ToDataException instead of an IOException. Adding ToDataException handling to queryOneLocator() should fix the problem.
