Apparently you have 295108 zones, maybe you can try one single rpz zone
with all 295108 fqdn's like
.....
12724[.]xyz IN CNAME .
21736[.[xyz IN CNAME .
.....
instead of one zone per fqdn, and see if the memory footprint changes
(both VMEM and RES)
Good luck!

significant improvement in both performance and memory usage.
Sorry, there's 295,108 hosts I'm serving up as 127.0.0.1 (for ad
blocking).
I zipped my entire /etc/bind directory (which includes all configs).
