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; };
