Can you send us the following? 1. Your named configuration. 2. Regular dumps over time of the statistics that are available via HTTP, as the named process grows. See the "statistics-channels" documentation in the manual. You can use curl or wget to dump them to a file. The standard tool for this on FreeBSD is fetch(1). E.g. fetch -o FILE "URL" In a script I usually also use '-q' to eliminate noise, but YMMV. I suspect most systems have wget and/or curl installed, but fetch is always present on FreeBSD. -- R.
