Not a bug, but an admission that overloading the SOA minimum TTL field as both minimum and default was not a good idea. The $TTL parameter "creates" a TTL of that value for each record not containing an explicit TTL. The SOA minimum TTL should be reduced to some fairly small value as it will be used for the TTL on negative cache entries and you typically don't want to cache these for very long. I set the minimum TTL to 15 minutes and $TTL to 1D (1 day) which is the same as $TTL 86400. (And the $TTL directive MUST be place before the SOA record. R.
