**Describe the bug** i tried to start a cluster in kubernetes with below nodes while setting pods memory limits 3G 2 clients nodes 3 masters nodes 3 Data nodes The problem that i found is that elastic pods dont see this limit and keep using the buffer/cache memory in the node which i see it increasing constatly can go beyond 7G, which lead to no memory in the nodes then when a pod is dead cant start again coz there is no memory , so i have to run echo 2 to drop cache to free the memory. is their a way to control how much elastic cache/buffer use cache? **Version of Helm and Kubernetes** : k8S v1.13.5 ---
