Why is named/zrd (named.log) reloading all the time ?

Hi,

Anyone have any idea why my zrd (Zonerunner on 11.5.1) is reloading all the time ? it's frequent but not regular (2 seconds, 2 minutes, 43 seconds .. could be anything) - I can't see anything in /var/log/gtm, audit or any other logs that suggest why it's happening. It's possibly 'normal' however my 11.2.1 box does not do this.

I'll open a case if needed but thought I'd check here first in case it is normal.

Heres a sample of named.log ..
