Memory cgroup out of memory

We have a Proxmox cluster with several nodes.

All nodes identical: 64GB RAM, 48 Xeon threads, 1x960ssd, ext4 noatime, vm.swappiness=1. Lately, swap was disabled via 'swapoff -a'

4 identical containers running same parsing-task: 20cpu, 16GB, noatime, Ubuntu 20.10 downloaded via ProxMox GUI.

Journaling is disabled at node and inside containers with:

Code:
echo "Storage=none" >> /etc/systemd/journald.conf
service systemd-journald restart

Nodes are hit by OOM-killer every 15 min or so.


Node's GUI shows less than 50% RAM used. Monitoring node with 'top' showed that oom comes when free memory == 0 and almost all free ram is consumed by kernel and allocated in 'buff/cache'. As far as I understand, kernel should release 'buff/cache' once there is memory request from applications, but in this case it probably doesn't.

I tried to overcommit RAM in LXC from 16Gb to 32Gb and it helped a lot. Now, oom visits only 5% of nodes but the problem is not 100% solved.
