Hi all,
I run a minimalistic Debian 10.10 container on Proxmox 6.2-6 dual host
stack.
It has 512 MB of memory assigned and most of the time uses about 10%.
Every time I try to ssh from it (using bash in web console) to a
different host the container crashes (powers off).
Syslog records the following:

the log says it got OOM killed. did you enable persistent journal inside
the container? if not, that might be the culprit (tmpfs usage in the
container gets accounted towards the container's resource limits).
`mkdir /var/log/journal && systemctl restart systemd-journald`
