Zonerunner GUI becomes unresponsive when attempting to view a large number of resource records.
- Zonerunner is a DNS client just like dig and nslookup. When it displays all the resource records in a zone, it makes an AXFR request to bind. - When it is asked to display a large number of records, the process can be CPU intensive and the GUI can become unresponsive.
DNS zones with a large number of resource records (over 60k) or when the cumulative number of resource records of all the zones exceeds 1000k records.
- Limit the number of records per zone to less than 60k. - Limit the cumulative number of records to less than 1000k
