I have another question when i using managers lib multiprocessing Maybe have exception.
my code is：
Session_lock.G_Process_Lock = multiprocessing.Manager().Lock()
def execute_select_command(command):
    try:
        with Session_lock.G_Process_Lock:
            values = []
            conn = sqlite3.connect(SQLite_DB_NAME)
            cursor = conn.cursor()
            try:
                cursor.execute(command)
                values = cursor.fetchall()
            except Exception as e:
                pass
            finally:
                cursor.close()
                conn.close()
            return values
    except Exception as e:
        print(e)
        traceback.print_exc()
    finally:
        pass

This code is possible to print out the information.

Traceback (most recent call last):
  File "C:/Users/Administrator/Desktop/Monitor_URL\Monitor_SQL.py", line 44, in execute_select_command
    return values
  File "C:\Users\Administrator\AppData\Local\Programs\Python\Python35\lib\multiprocessing\managers.py", line 949, in __exit__
    return self._callmethod('release')
  File "C:\Users\Administrator\AppData\Local\Programs\Python\Python35\lib\multiprocessing\managers.py", line 716, in _callmethod
    conn.send((self._id, methodname, args, kwds))
  File "C:\Users\Administrator\AppData\Local\Programs\Python\Python35\lib\multiprocessing\connection.py", line 206, in send
    self._send_bytes(ForkingPickler.dumps(obj))
  File "C:\Users\Administrator\AppData\Local\Programs\Python\Python35\lib\multiprocessing\connection.py", line 280, in _send_bytes
    ov, err = _winapi.WriteFile(self._handle, buf, overlapped=True)
TypeError: WriteFile() argument 1 must be int, not None

This maybe seem like a lib problem.
