Google App Engine：upload_data失败，因为在DevServer上“目标机主动拒绝了它”

Question

我正在尝试使用DevServer将数据从CSV上传到我的应用程序：

appcfg.py upload_data --config_file="DataLoader.py" --filename="data.csv" --kind=Foo --url=http://localhost:8083/remote_api "path/to/app"

结果：

Application: appname; version: 1.
Uploading data records.

[INFO    ] 1230 entites total, 0 previously transferred
[INFO    ] 200 entities (218274 bytes) transferred in 25.8 seconds
[INFO    ] Some entities not successfully transferred

当我尝试后续时间时，实体的计数在200-850之间转移了范围。

这里发生了什么？通常这可以正常工作。导航到 http://localhost:8083/ 工作，应用程序运行良好。 （除了缺乏数据。）

通过添加命令行选项将线程数减少到4 --num_threads=4

如果仍然不起作用，则会进一步减少线程数。
