+    Pod-Memory-Hog fault consumes memory resources of specified containers in Kubernetes pods.
+    - Causes memory resource consumption on specified application containers using cgroups and litmus nsutil that consume memory resources of the given target containers.
+    - It tests the application's resilience to potential slowness/unavailability of some replicas due to high memory load.
+    - The application pod should be healthy once chaos is stopped. Expectation is that service-requests should be served despite chaos.
