Bad page map in process khugepaged

My YunoHost server

Hardware: proxmox VM
YunoHost version: latest
I have access to my server : Through SSH | through the webadmin | direct access via keyboard / screen | …
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no

Description of my issue

i encountered this screen AND the system seems halted BUT it KEEPS consumming CPU Resources:


I wanted to know if i am falling into a bad practice having yunohost installed on a proxmox VM or if there is some incompatibility that is making something in my yunohost installation manage the memory poorly (i hope i am making myself clear)…

This started to happen since latest update but maybe it does not necesarily have to do with it…

Thank YOU for your insights!

just in case here i transcript the relevant log parts:
