After 1 month, seems to work for me.
i used the following commands for the affected server:

apt install proxmox-kernel-6.5.13-5-pve-signed

apt install proxmox-headers-6.5.13-5-pve

proxmox-boot-tool kernel pin 6.5.13-5-pve

Thk.

Hi all. I've been using Proxmox since version 5. Each version had its bugs. But in version 8, a strange phenomenon happens. Proxmox increases memory consumption every day. I have an Hp 360 G9 server with 256GB and a few virtual machines that have a total of 125GB allocated (if each virtual machine consumed all the allocated memory) and it's up for 21 days, during which time the memory has reached 185GB. I mention that I don't use ZFS, NFS, just smb. At version 7 of proxmox I didn't encounter this situation. Now I'm using Proxmox 8.2.2 and today I updated to 8.2.4

i used the following commands for the affected server:

apt install proxmox-kernel-6.5.13-5-pve-signed
apt install proxmox-headers-6.5.13-5-pve
proxmox-boot-tool kernel pin 6.5.13-5-pve

Work for me.

Work for me.

Good for you. But maybe try one of the newer kernels. In recent history a memory-leak issue was fixed. This may affect your system.

i installed the new kernel 6.8.8-4. About 20 days I have to wait to see if the memory grows

 

[monokeb]

So far. So good. 30days. After update, seems to be stable.

apt install proxmox-headers-6.5.13-5-pve

Why have you installed the headers?

Hello,
I have the same issue, my last Proxmox update was on June 22nd and since that update I got the problem of the memory constantly raising.

With a total 16GB of memory, and with 4GB directly consumed at startup, the remaining GB are slowly consumed with a time window of around 1 week.

Yesterday I did a system update (I had a kernel update on that) and now after 24 hours the memory consumption seems to be stable a 4.90/5.00GB. I'm now running on Linux 6.8.12-1-pve (2024-08-05T16:17Z)

Now I leave it for about 1 week and see how it goes.
