Since more than a week, each day my mini server has a oom and all containers are getting killed by oom. How do I find the reason?
Bonus: how can they automatically restart again. I have to do it manually.
- journalctl shows the oom event
- Container limits you can limit container resouce usage
- also you can look at container stats to maybe identify the culprit. Or cyclically write the stdout of ps to a file to identify the memory hungry process.

OOMs happen because your system is out of memory.
The kernel tries to “blame” a process and will kill it, as you’ve seen, but ultimately, you may know better than it which is acting in a way you don’t want”.
It may be that you simply don’t have enough memory to do what you want to do. You might be able to get by by adding more paging (space.

Thank you, I’ll try to setup a systemd timer with that
