[solved] Why my debian VM is sometimes off?

[LGTMozart]

Hi everybody!

I have a PVE HPE on Proliant 360DL Gen 10 with 16 cores (Intel(R) Xeon(R) Silver 4110 CPU @ 2.10GHz) and RAM 128 Go. It runs 6 VM (3 debian, 2 W10, 1 Windows Serveur 2016) and sometimes 1 or 2 VM is off (I don't shutdown the VM). Since I upgrade to PVE 8.2.4 one week ago, just one VM is sometimes off (debian VM) and I don't understand why.

I think it could be lan-shutdown so I would know if I can know the time when this VM is shutdown.
Could it be a RAM issue ?

Others idea ?

My thinking was a good idea. It was a lan-shutdown, not a pve issue.
