memory leak problem

[sponner]

my proxmox ram usage: https://prnt.sc/s8aqcs --
86.79% (109.18 GiB of 125.80 GiB)

total vm's usage: https://prnt.sc/s8aqh8

my usage is max 40-50 gb average but proxmox is showing 109 gb ram usage

if i start a vm over the free amount
which I give the most ram, turns off by itself

how i can resolve this problems ?

note: qemu-agent installed on al vm's and qemu is active

do you use zfs? if yes, that can take up to half of the memory by default, see https://pve.proxmox.com/wiki/ZFS_on_Linux#_limit_zfs_memory_usage

unrelated to virtual guests. ZFS is a storage type that can be setup during the installation of PVE.

do you use ZFS on your PVE? that would explain the high memory usage. if yes, refer to the link @dcsapak posted

are we doing this on proxmox?

ZFS is indeed not a memory system but a storage. however if you read the previous posts carefully you would know it can use a lot of memory...

you were asked a simple question which you didn't answer:

do you use ZFS on your PVE?

please answer so we can help...

most likely the process is terminated by OOM-killer, which means you need to make sure you're not running out of RAM.

PVE needs some amount of RAM to function itself, so you can't give all the memory to VMs

i not using zfs

how i can disable OOM-killer ?

Add either enough memory or do not over commit it so that you never get into an Out-Of-Memory situation, there's no other way.

i want to add more vms like vmware for example

The tricks they provide can be replicated with KSM and/or ballooning: https://pve.proxmox.com/wiki/Dynamic_Memory_Management

But, memory cannot be over committed, not really possible for vmware either - it only works as long as not all VMs require the actual memory, once they do use more memory than available there will be OOM kills too in vmware systems.
