Hello,
looking at the XSTAT of an authoritative server (no fetch-glue and no
recurse) I am
still puzzled by the amount of non-authoritative answers it gives.
Here an extract of relevant numbers :
RR=5301 .. SSysQ=5325 SAns=11321054 .. SFwdQ=0 RQ=11437731
.. SNaAns=594874
(numbers cover 10+ days)
Given this server answers only from local data, SFwdQ=0, how comes half
of
the answers are non-authoritative ?
By the way, I understand System Queries are unsollicited by incoming
queries but
come from the internal operation of the name server. It was my
understanding the
querying for the updated list of root servers are such system
queries. But what
others fall in this category that can explain the amount of 5000+ ?
Thanks in advance,
Marc
