Hello - just an observation which the devs might want to look into:
The bind config that sipxecs generates has a "statistics-file" statement, but, "zone-statistics" statement does not seem to be set anywhere, unless I'm not finding it.
$ cat /etc/named.conf | grep stat
statistics-file "/var/named/data/named_stats.txt";
The default for "zone-statistics" is "no" so, the stats file that's specified will not be written.
I could be wrong, but, just an observation.
