Does the host get its IP from DHCP?
If yes, I'd assume the check_dig-based service check tried to verify
that the host itself had a certain IP but it got a different one
when you brought it back up, although why you'd want to resolve the
name of a host with dynamic ip-assignment is beyond me.

Considering the successes of the wars on alcohol, poverty, drugs and
