用pymongo不断得到DuplicateKeyError

Question

Pymongo几周来一直很好，直到我遇到以下错误：

    Traceback (most recent call last):
      File "main.py", line 14, in 
        main()
      File "main.py", line 11, in main
        downloader.process()
      File "/mnt/vdisk/crawler/eurostat/downloader.py", line 25, in process
        self.processHelper()
      File "/mnt/vdisk/crawler/eurostat/downloader.py", line 61, in processHelper
        self.base.insert(documents)
      File "/usr/local/lib/python2.7/dist-packages/pymongo/collection.py", line 359, in insert
        continue_on_error, self.__uuid_subtype), safe)
      File "/usr/local/lib/python2.7/dist-packages/pymongo/mongo_client.py", line 852, in _send_message
        rv = self.__check_response_to_last_error(response)
      File "/usr/local/lib/python2.7/dist-packages/pymongo/mongo_client.py", line 793, in __check_response_to_last_error
        raise DuplicateKeyError(details["err"])
    pymongo.errors.DuplicateKeyError: E11000 duplicate key error index: test.eurostatdata.$_id_  dup key: { : ObjectId('50fd056757b924675af21a0e') }

_id绝对不是该领域之一。我总是依靠mongodb来生成自己的_id，所以我之前从未遇到过这种问题。

插入代码：

documents = []
for key in split_table_data:
    document = ele
    document["title"] = ele["title"]
    document["table_data"] = split_table_data[key]
    document["cols"] = colsHeader
    document["subTitles"] = key
    documents.append(document)
self.base.insert(documents)

我使用最新的pymongo包和最新的mongodb。

唯一可能导致此问题的是我尝试插入超出大小限制的文档。

我试过了

  

db.repairDatabase（）

     

db.test.validate（）
