Android случайным образом вызывает mediaPlayer onCompletion при изменении ориентации при потоковой передаче видео rtsp

Ищу уже несколько дней и не могу понять, почему mediaPlayer случайным образом срабатывает onCompletion при изменении ориентации устройства. Похоже, что устройства с большим объемом памяти, такие как более мощные планшеты, не так часто выходят из строя, но иногда тоже.

Мой MediaPlayer работает во фрагменте, и я попробовал метод постоянного MediaPlayer с вызовом setRetainInstance (true).

Как подсказка, некоторые устройства иногда сообщают в LogCat, что слишком много работы выполняется в основном потоке, когда это происходит.

Вот мой код фрагмента:

final public class MediaPlayerFragment extends Fragment implements OnCompletionListener, OnPreparedListener, OnBufferingUpdateListener, OnInfoListener, OnErrorListener, SurfaceHolder.Callback {

    /**
     * 
     */
    public final static String  TAG                 = "MediaPlayerFragment";

    private MediaPlayer         mp                  = null;
    private SurfaceView         surfaceView         = null;
    private String              path;

    // create an handler
    private final Handler       myHandler           = new Handler();

    private static final double ASPECT_RATIO        = 4.0 / 3.0;

    /**

                                                        }

Может ли кто-нибудь увидеть большую ошибку в том, как я обрабатываю SurfaceView MediaPlayer или что-то еще, чтобы приложение вылетало.

Вот лог от LogCat после его двойного поворота и при втором изменении ориентации он разбился:
