Hi James,
If you are only worried about Disk Space Issues, that is part of a BIND Config and can be changed at will.
file "/var/log/query.log" versions 7 size 250m ;
file "/var/log/query.log" = File location and file name. You can change any of this to a location on the Big-IP that has lots of space.
version 7 = Keep a total of 7 files (6 Archived / previous and 1 Active)
size 250m = Each log file size should reach 250 meg, then roll the log file and create a new one.
These options allow you to plan how much HDD Space your Query Logs will take, and how much history you want to keep.
Some of my DNS Servers take almost 2 million queries per day and they only roll the logs maybe once every 2 or so days.
Hope this helps.
