My server (fedora) stops all podman containers after 2-3 hours since 3 days. I can start all containers again, and the same happens after a while. I do not know where to look for the problem.
In top, I found a oom message. I assume that the system runs out of memory and stops all services. How can I find the problem? I can’t find anything in the container logs.
I can see that systemctl status is always starting. It doesn’t become “running”. But I do not know how to proceed.
I’ve got way too much RAM for swap being useful at all. Good idea though.
There is no such thing as too much RAM…
If something you’re running has a memory leak then it doesn’t matter how much RAM you have.
You can try adding memory limits to your containers to see if that limits the splash damage. That’s to say you would hopefully see only one container (the bad one) dying.
Then you didn’t understand how the system uses swap.

They could mean that they have swap but it’s not being used.
