## Warnings about kernel support

If your operating system does not enable certain capabilities, you may see
warnings such as one of the following, when you run `docker info`:

```none
WARNING: Your kernel does not support swap limit capabilities. Limitation discarded.
```

```none
WARNING: No swap limit support
```

You can ignore these warnings unless you actually need the ability to
[limit these resources](../../../config/containers/resource_constraints.md), in which case you
should consult your operating system's documentation for enabling them.
