Google App Engine Bulkloader“线程意外死亡”

Question

我正在尝试使用bulkloader功能将一个中等大小的csv文件上传到google应用程序引擎，但它似乎在某种程度上失败了，结果如下：

[INFO    ] Logging to bulkloader-log-20110328.181531
[INFO    ] Throttling transfers:
[INFO    ] Bandwidth: 250000 bytes/second
[INFO    ] HTTP connections: 8/second
[INFO    ] Entities inserted/fetched/modified: 20/second
[INFO    ] Batch Size: 10
[INFO    ] Opening database: bulkloader-progress-20110328.181531.sql3

...............................................................[INFO    ] Unexpected thread death: WorkerThread-7
[INFO    ] An error occurred. Shutting down...
.........[ERROR   ] Error in WorkerThread-7: <urlopen error [Errno -2] Name or service not known>

[INFO    ] 1740 entites total, 0 previously transferred
[INFO    ] 720 entities (472133 bytes) transferred in 32.3 seconds
[INFO    ] Some entities not successfully transferred

它上传了我试图上传的19k个条目中的大约700个，我想知道为什么它失败了。我检查了csv文件中的错误，比如额外的逗号可能会使python csv阅读器脱离，并且非ascii字符已经被剥离。

取消批处理限制(batch_size)和rps限制(rps_limit)有效，我使用1000作为批处理大小，rps限制为500：

appcfg.py upload_data --url= --application= --filename=  --email= --batch_size=1000 --rps_limit=500
