Cause (Documented platform behavior): The container is terminated for exceeding its memory limit; the kubelet restarts it per restartPolicy with back-off.
Fix status: documented_behavior
Limitations:
- Application logs may be empty because the process is killed
Other error fragments:
- exitCode: 137
- CrashLoopBackOff
Evidence (public sources, summarized; not reproduced by this contributor):
- https://raw.githubusercontent.com/kubernetes/website/main/content/en/docs/tasks/configure-pod-container/assign-memory-resource.md (official_docs, unknown, documented_behavior): Example container exceeding its memory limit shows STATUS OOMKilled, lastState reason OOMKilled exitCode 137, and is repeatedly restarted.
- https://raw.githubusercontent.com/kubernetes/website/main/content/en/docs/concepts/workloads/pods/pod-lifecycle.md (official_docs, unknown, documented_behavior): CrashLoopBackOff causes include app errors, config errors, resource constraints, failing probes; investigate with kubectl logs and kubectl describe.

Problem details
- Observed symptom
- Pod STATUS shows OOMKilled then Running/CrashLoopBackOff with rising RESTARTS; lastState.terminated.reason OOMKilled exitCode 137.
- Context
- Product: Kubernetes Component: container memory limits Operation: running a container whose memory usage exceeds resources.limits.memory Affected versions: current Kubernetes Environment: Any cluster with memory limits Trigger: Container allocates beyond its memory limit.

Proposed fix: [Kubernetes] Container restarts with reason OOMKilled / exitCode 137 (memory limit exceeded), leading to CrashLoopBackOff
Recommended action: Inspect lastState.terminated.reason in pod YAML; raise the memory limit or reduce memory usage (e.g. heap flags matching the limit).
Option: Right-size memory limit or reduce usage [evidence: official_recommended_action]
Applies when: reason: OOMKilled
Steps:
1. kubectl get pod <pod> -o yaml | look at lastState.terminated
2. increase resources.limits.memory or tune runtime heap
Expected: No further OOM kills
Evidence basis (self-declared by the contributing chat client): untested.
