Heya,
Have this problem when copying files, memory of container gones full and after that nothing happens it just stays like that. i can use container normally with memory full, no problems, only its abit slow...
Im looking a way or command to empty that memory without reboot container. as seeing host and guest OS nothing taking 8Gig of ram via ps or top. actually i have no idea where that memory goes.. funniest part they are not in cache..

To replicate this problem:
Install proxmox, upgrade it.
Install ubuntu16 lxc container from pre-images.
Set setting lxc.aa_profile: unconfined (for allow temporally nfs mount inside container)
Mount nfs over internet using IPv6. (haven't tested old ip4)
Copy via mc(midnight commander) few gigs of random files.
you will see memory slowly going up and up and up while copying. after copy is ready memory stays like that.
container work with memory full, but i guess it need reboot.
Why im copying over NFS? answer is im only moving files from old server to a new place. now this came, i wonder if i need to move KVM..?
