Why don't you fix the nameserver instead ?=20=20

Given a good platform and a recent version of bind it=20
will run by itself for years ...

Yes.  Your "test" is faulty. It won't diffrentiate between=20
your server has stopped and your connection to whatever you test with
is broken.  And it won't test your clients abilyties to resolve ( and
that is a far more frequent problem then bind getting ill)
