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.
If you saw an OOM anything, it’s getting OOMkill’d by the kernel trying to keep the machine up. Check syslogs and dmesg, and it should say what was killed, and there’s your problem container. You probably have a memory leak, so just check your container stats every so often and see what is growing out of control with memory usage.
Enable swap regardless. Would also help to know what you’re running.
