When restarting system services via the terminal, you might encounter a message like this:
This is completely normal and nothing to worry about.
We use the --oom-kill-disable flag for critical system containers such as the Caddy web server, OpenPanel UI, and DNS services. This flag instructs the kernel not to terminate these containers if the system runs out of memory, ensuring they remain up and running.
If your kernel supports this option, it will be applied as intended. However, if the kernel does not support it, Docker will simply display a warning message like the one above when starting the container.
You can safely ignore this message.
It does not indicate a problem, and no further action is needed.
