Fixing a memory leak in Kubernetes with a single line of code.

I love such debug stories because you can read them almost as a thriller or a detective literature. Also, this case is very interesting indeed and it took that team a couple of months to figure it out.

A takeaway for myself:
- It‘s useful to have a dashboard (and potentially a monitor) that shows the difference of the node memory usage and the memory usage by pods.
