These messages are normal. They show that the name server is running
normally: they're not an indication of a problem.
Stefan> Mar 27 14:15:25 pc0 named: Cleaned cache of 34 RRsets
34 resource record sets were expired from the name server's cache
since the last time it cleaned up the cache.
Stefan> Mar 27 14:15:25 pc0 named: USAGE 954159325 954155726 CPU=0.5u/0.25s CHILDCP U=0u/0s
The name server started at 954155726 seconds after the UNIX epoch and
the messages were logged at 954159325 after that time: Mon Mar 27
12:15:26 GMT and Mon Mar 27 13:15:25 GMT respectively. In the hour the
name server has been running, it has used half a second of CPU time in
user mode and 0.25 of a second executing in system mode. No CPU time
was needed for child processes forked by the name server.

received since it started: 358 requests for A records, 1 for a SOA

This is a breakdown of the queries the name server has made and the
answers it has given. It received 114 answers from other name servers,
3 of which were NXDOMAIN: "so such host/domain". It received 566
queries, 6 of which were duplicates. Of the 474 answers it sent, 71
were non-authoritative answers and 39 were NXDOMAIN because the names
being looked up did not exist.
Stefan> How can I disable this!
In BIND8 setting the statistics-interval to zero will do this but why
would you want to ignore such useful information? By default, the name
server generates these messages every hour.
