ProxMox VM show out of memory

[tfirkins]

I recently noticed that Proxmox shows the memory usage of an OPNSense Virtual Machine at 100% consumed, in essence, out of memory. Yet, when I log into the Web UI of the OPNSense VM, it shows memory at only 23% consumed, and it is operating normally. What might be causing this discrepancy?

See https://pve.proxmox.com/wiki/Upgrade_from_8_to_9#VM_Memory_Consumption_Shown_is_Higher :

FreeBSD is known to not report memory usage details, which includes popular firewalls like pfSense or OPNsense.

Thanks for the swift response.
