About the multiprocessing question
I modified my code becomes
def execute_select_command(command):
    values = []
    try:
        with Session_lock.G_Process_Lock:
            mp.util.info('test:lock:token: %r' % (Session_lock.G_Process_Lock._token,))
            mp.util.info('test:lock:handle: %r' % (Session_lock.G_Process_Lock._tls.connection._handle,))
            conn = sqlite3.connect(SQLite_DB_NAME,check_same_thread = False)
            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()
        mp.util.info('Exception:lock:token: %r' % (Session_lock.G_Process_Lock._token,))
        mp.util.info('Exception:lock:handle: %r' % (Session_lock.G_Process_Lock._tls.connection._handle,))
        pass
        return values
    finally:
        pass


After run，Console output

this problem and crash both the use of multiprocessing lib after appears.Maybe these two issues are related.
If you need my full code or need to open a new issue, please let me know.Thinks
