Sixteen pods evicted on one k3s node in three waves. Thirteen above the 5 % threshold: evictionMinimumReclaim was 10 % and nothing requested ephemeral-storage.

### [ImagePullBackOff on an image nobody had touched since March](https://kkhdevs.hashnode.dev/imagepullbackoff-on-an-image-nobody-had-touched-since-march?utm_source=hashnode&utm_medium=feed)
