Memory utilisation under Proxmox is nothing to worry about. What you see is normal. This is utilisation reporting from an system running for the last 4 years.
You should always check stats from inside HA. Notice the difference in memory utilisation. HA provides the correct info. (settings → system → hardware)
Never had the time or inclination to investigate but have noticed usually VMs created with cpu type host report the correct memory utilisation in Proxmox. VMs created with cpu type kvm64 or qemu64 report your findings.
One last thing which might be useful; if you click on the more button you get an overview of the HA container system.
System created with cpu type host.
my VMs are with cpu type host.
also memory shown in proxmox looks good compared to “top” command in cli of homeassistant (even proxmox seems so show a bit less)
“very nice”.
i knew about the hardware information within HA but didn’t check it yet during “this issue”, but yes, here is a big difference between HA & proxmox.
but HA CLI shows higher usage than the GUI here. (here i would just use 0.7GB 
guess, i will leave it as it is, as long as HA is doing its job, i’m fine with it. i have my backups, just in case 
Same issue with me, HAOS since January using incremental ram of approx 0.2mb/second. I have installed it on Casa OS via the official repository but seems like the issue has not been resolved for me after the lastest update too.
I am having to reboot the system twice a day. As it piles upto 8gb using 100% allocated to it rendering all my automations useless.
I am experiencing the same issues. VM on Proxmox, maxing out the 9 GB of RAM to the VM very quickly.
I’m also seeing high Memory Usage on the Proxmox summary page.
It seems no matter how much GiB is allocated to the VM, it will eventually use it up and report high memory usage. I have allocated 8 GiB to my VM.
I think there is something not quite right with the values shown in Proxmox.
I’ve read similar stories on the Proxmox forum. It sounds like a caching related matter.
Here’s some details of what I found in my system to back up my theory:
Seems that HA and htop are aligned.
I went to the trouble of increasing my Proxmox host RAM from 16GB to 64GB, but my HA VM still ramps up the amount of RAM it uses after a day or two.
After a little digging, I think I found a co-related cause . . . the HA database.
I just did a purge of the database and it immediately dropped the memory usage reported in Proxmox from 7.5 Gib to 4.0 Gib.

I just used the Developer Tools>Services feature
