how to check if a slave zone is expired

[Barry Finkel]

I review the BIND syslogs on my servers daily.  The syslog will
tell me if any slave is having problems loading a zone.
I expect that the hostmasters at my off-site slaves do the same.
If I slave a zone for someone else, and I see problems, I contact
the owner of that zone.
