Thank you, I will check it out.
I just sent the message wondering whether someone had seen something similar.
It is a bit shocking given that 9.18 achieved better memory efficiency than the
previous versions if I remember well.
For now, what surprised me is:
Server one, highest query load, mostly clients querying the typical A records.
Server two, lower query load, pattern is different receiving lots of MX queries
from mail servers.
Both are running FreeBSD 14.2.. Bind compiled from ports.
Server one: 9.18.32
boot time: Wed, 12 Feb 2025 14:04:42 GMT
last configured: Fri, 14 Feb 2025 07:33:09 GMT
VM size: 632 MB, RES 446MB
Second two: 9.20.5
boot time: Thu, 13 Feb 2025 09:44:04 GMT
last configured: Thu, 13 Feb 2025 10:33:47 GMT
VM size: 1079MB, RES 945 MB.
The “sizes” are those reported by top (different from the Linux version).
I will keep monitoring and let you know.
Borja.
