cache server not stable?

[Kevin Darcy]

What are you publishing in the NS records for the zone? Just the
master? Or the master and one or more slaves? If you have slaves, is
replication occuring properly? Sounds like your caching server is
sometimes going to a slave that doesn't have up-to-date information
about the zone.
