Thanks for your replies! I didn't have a sense of adding a semaphore on writing to pickle data before, so corrupted the data. Since my data was colleted in the daily usage, so cannot re-run the code and regenerate the data. In order to avoid corrupting my data again and the complicity of using a semaphore, now I am using json text to store my data. -- https://mail.python.org/mailman/listinfo/python-list
