    Sorry for the multiple posts... I didn't know the picture would not go

    I have been graphing my named.stats file and noticed that every hour on
the hour
    named does something.. AND I can't explain it.. but here is the info..

    Can somebody explain this??

    It looks like named does something with its queries every hour for some
    maybe a refresh or something?  Maybe I am grasping at straws.  The Green
in the graph
    is RQ and the Blue line is SNaAns


    [named at orion named]$ cat /etc/named.conf
    options {
            cleaning-interval 720;
            directory "/var/named";
            interface-interval 0;
            pid-file "/var/run/named/";
            notify no;
            statistics-interval 60;
            host-statistics yes;
            allow-transfer {

    logging {
            channel named_log {
                    file "/var/log/named/named.log";
                    severity info;
                    print-category yes;
                    print-severity yes;
                    print-time yes;

            category lame-servers { null; };
            category cname { null; };
            category default { named_log; };
