pymongo操作错误

Question

我从我的MongoDB一路上得到了很多纪录，我得到一个错误

File "C:\database\models\mongodb.py", line 228, in __iter__ 
    for result in self.results: 
    File "C:\Python27\Lib\site-packages\pymongo\cursor.py", line 814, in next 
    if len(self.__data) or self._refresh(): 
    File "C:\Python27\Lib\site-packages\pymongo\cursor.py", line 776, in _refresh 
    limit, self.__id)) 
    File "C:\Python27\Lib\site-packages\pymongo\cursor.py", line 720, in __send_message 
    self.__uuid_subtype) 
    File "C:\Python27\Lib\site-packages\pymongo\helpers.py", line 99, in _unpack_response 
    cursor_id) 

pymongo.errors.OperationFailure: cursor id '866472135294727793' not valid at server 
Exception KeyError: KeyError(38556896,) in <module 'threading' from 'C:\Python27\lib\threading.pyc'> ignored 

这是什么意思，我如何解决它。我不知道这是否是重要的，但我没有 使用from gevent import monkey; monkey.patch_all()当我打开连接
