pool mysql error - not catch by try\except?

[korenron]

Hello,
I'm using Pool function to run several mysql command 'update'

I guess I have some connection problems because I'm gettig this error:

mysql.connector.errors.OperationalError: MySQL Connection not available.

maybe netwrok isuses or my sql server is down - I'm checking it now

but why the try didn't catch the exception and continue ?

            try:
                mycursor1 = mydb.cursor()
                sql1 = f"update david.david_test set ROU_COMMENT = '" + Upload_Status + "',SendTime=NOW() where rou_ip = '" + Unit_IP + "';"
                print(Upload_Status)
                mycursor1.execute(sql1)
                mydb.commit()
            except mysql.connector.Error as err:
                print("Something went wrong: {}".format(err))
            except Exception as e:
                print(e)
                print('MYSQL Problem?')

is it beacuse the Pool function is not also in try\except?

if __name__ == '__main__':
    StartTime = datetime.now()
    Device_List = getListFromMysql()
    Final_List = []
    with Pool(10) as p:
        Final_List = p.map(GetUplaudFies, Device_List)
       

Thanks,
