Thanks for the help. Of course, we want a more predictable result from computers, but it turns out the opposite.
I have attached the information.
Today, the memory consumption is as follows RAM usage 15.46% (4.72 GiB of 30.52 GiB). Only one virtual machine is running. No actions are performed on it. Also, nothing is being done on the hypervisor itself. Compared to the latest version, in this version of proxmox 7.4-3, memory leakage occurs in a very slow mode.
