paramiko sftp服務器連接丟失

Question

我想使用paramiko sftp複製大文件（〜650mb）文件。我能夠複製小文件，但當我嘗試複製大文件時，我看到以下錯誤。我能夠通過使用sftp直接從終端複製文件。

此外，只有在閱讀了一定數量的字節後纔會拋出。我介紹裏面sftp_client.py print語句，這是輸出（字節）

reading bytes data_size: 11 
reading bytes data_size: 28 
reading bytes data_size: 28 
reading bytes data_size: 32776

reading bytes data_size: 32776 
reading bytes data_size: 32776 
reading bytes data_size: 32776 
reading bytes data_size: 32776 

爲什麼連接在文件中被丟棄這是我不清楚。有關如何處理這個問題的任何建議？

謝謝！
