問題原因：

@Override
public void onDestroyView() {
    Logger.v(TAG, "@onDestroyView. remove fragments. by FragmentTransaction.");
    super.onDestroyView();
    FragmentTransaction trac = getFragmentManager().beginTransaction();
    trac.remove(hotFragment);
    trac.remove(channelFragment);
    trac.remove(recmdFragment);
    trac.commit();
    hotFragment = null;
    channelFragment = null;
    recmdFragment = null;
    linearLayout1 = null;
}

問題出在上面代碼片段中的trac.commit()語句！

把onDestroyView方法去掉就OK！
