Title: Increase in memory usage

- disable host discovery

after upgrade 26.1 to 26.1.1

While the absolute amount is small, percentage-wise, it seems to be about a 50% increase. Usually, it hovers in the low 1000MB range.

Mine fluctuates. I have hostwatch enabled and it's currently sitting at ~1.2GB, but I've seen it as low as 800-900MB and as high as 2+GB depending on when I check.

In either case it's still within the requirements range: https://docs.opnsense.org/manual/hardware.html

don't user ids/ips
low traffic

I haven't changed any settings, but looking at the monitoring graphs, RAM usage definitely went up after the 26.1.1 upgrade.

I have a very basic setup and my RAM usage has always been around 2 GB so I would say it's nothing to worry about ?!

An Idle OPNsense, with only a shaper enabled and some tunables memory usage is something around 1G with opened GUI.
This is with no traffic and like 10 states opened. And hostwatch disabled.

I assume your OPN is in PROD?
It seems to me you are in the spec.
