File descriptors and inotify watches can still be exhausted. In somewhat older versions also pids. If you allocate memory fast enough(if you're a best effort pod), oomkiller instead of kubelet evictions happen, which can be kind of unpredictable. Similarly you can fill up storage. You don't want to be colocated with bad pods.
