I have successfully download my data from datastore on my Mac OS X 10.8 (SDK 1.6). However when I’m using appcfg upload_data I get the following error; any idea ?

appcfg.py upload_data –url=http://localhost:8081/_ah/remote_api –filename=db_backup_2012_Nov_3

ERROR:

[INFO ] Connecting to localhost:8081/_ah/remote_api [INFO ] Starting import; maximum 10 entities per post ………..[INFO ] Unexpected thread death: WorkerThread-2 [INFO ] An error occurred. Shutting down… ……..[ERROR ] Error in WorkerThread-2: [ERROR ] Error in WorkerThread-7:

    I solved the problem by limiting the number of threads to 1 when runnign appcfg upload_data:

    appcfg.py upload_data –url=http://localhost:8081/_ah/remote_api –filename=db_backup_2012_Nov_3 –num_threads=1

    The dev app server seems to be dropping threads. Perhaps because of having “threadsafe: no” in app.yaml!
