Challenge on Kubernetes

A multi-container Pod has one container stuck in CrashLoopBackOff. The Deployment sets a generous pod-level memory limit, yet raising it changes nothing. Find which container is dying, work out where its real limit comes from, and bring the whole Pod to a stable Running/Ready state.
