MIAB memory usage

I was surprised to find that MIAB processes are using 600MB of the 1GB ram on my server. Is this normal?

I’m not using the MIAB nameserver (I’m on Cloudflare). In this situation is there an easy way for me to disable all the MIAB nameserver stuff (nsd, named?) to save some RAM?

Disabling the name server isn’t supported. Doing so may make your MIAB unpredictable, and it will be restarted on every update.
