pymongo operation error

I am getting a lot of records from my MongoDB and along the way I get an error 

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

What does this mean and how do I fix it. I don't know if it matters but I did use from gevent import monkey; monkey.patch_all() when I opened the connection

When the cursor has been open for a long time with no operations on it, it(the cursor) can timeout -> this leads to the error

you can set timeout=False in your find query to turn the timeout off
