我正在尝试遍历此循环:
for doc in coll.find()
我在第 100,000 条记录中收到以下错误。
File "build\bdist.win32\egg\pymongo\cursor.py", line 703, in next
File "build\bdist.win32\egg\pymongo\cursor.py", line 679, in _refresh
File "build\bdist.win32\egg\pymongo\cursor.py", line 628, in __send_message
File "build\bdist.win32\egg\pymongo\helpers.py", line 95, in _unpack_response
pymongo.errors.OperationFailure: cursor id '1236484850793' not valid at server
这个错误是什么意思?
