私はMysqlを使用してPython 2.7でマルチスレッドプログラムを持っています.私のマルチスレッドプログラムでは、スレッドの一般的な機能はprocess_submissions. その中で、 を使用して専用接続を作成しconn=pool.dedicated_connection()ます。関数process_submissionsは、この接続connを別の関数に渡します。別の関数rt_scriptsは、(渡された接続を使用して) テーブルを照会し、に戻ります。process_submissionsしかし、次のエラーが発生します。

このような接続を渡すと問題が発生しますか、それとも何か他のものですか??
