From this message I would assume that the following events
occured.
This is the first installation of 4.9{.X} on this machine.
The old cache files were NOT removed prior to starting the new
nameserver.
What has happened here in the glue A records in the old cache
files were read into the internal cache with a higher clev than
the real A records. A zone transfer then occured for the zone
from which they were loaded and the A records were `lost'.
4.9.2 depends on the cache files having been made with a 4.9.2
named-xfer.
Mark.
