Curious, I do have a very similar case at the moment with a slab of ~155GB,
out of ~190GB RAM installed.
I am not sure yet what causes it but things I plan to investigate are:
* hanging NFS mount
Okay, to rule storage issues out, this setup has:
- root filesystem as ext4 on GPT
- efi system partition
- two LVM PVs and VGs, with all VM storage in the second LVM VG
- no NFS, no ZFS, no Ceph, no fancy userland filesystems
* possible (PVE) service starting too many threads -> restarting each and
checking the memory / slab usage.
Do you have a particular service in mind?
Not at this point. I would restart all PVE services (systemctl| grep -e
"pve.*service") one by one to see if any of it will result in memory
being released by the kernel.
If that is not the case at least they are ruled out.
