Yes, give us more info. We can only guess from what we've been told.
Perhaps the slave forwards all requests to the master, perhaps the zone
was never properly loaded on the slave, so it was always requesting the
info from your master. If it was the latter, some info would be in it's
cache, but probably not all. That would make it fail transiently.

Please share more on the configuration of your master and slave, and
look in the logs of your slave for errors. I have a feeling you'll find
some.

OBTW, don't do anything else before you upgrade BIND. You've probably
already been rooted. I get scanned all the time from redhat boxes
running BIND, that appear to have been rooted.
