ARC RAM usage

[Isabella Borgward]

Just looking over my firewalls in central management, one firewall stands out above all the others with RAM usage at 85%. Every other box is 25-35%. It seems to be ARC, which I believe is part of ZFS.
All firewalls are on 26.4 or 25.10 and have 8GB of RAM. Why would ARC usage be so high on one firewall?

In theory ZFS should never use more than 50% of that IIRC so you should have nothing to worry about despite these values.

However...

Why would ARC usage be so high on one firewall?

Do all of them have Hostwatch Enabled or not ?

It's a process that's constantly active and gave many of us all sorts of issues after it's release and that's why many of us also have it set ti Disabled !!

So you could try that too and see if things will change ?
Might need a reboot just to be sure... :)
