Before you change production

This page includes public source URLs in the imported troubleshooting record. Compare those references with your version and environment before applying changes.

Reproduce the smallest failing action and save non-secret logs before changing configuration.
Check versions for Kubernetes, related SDKs, package managers, CI runners, and hosting providers.
Change one setting or dependency at a time, then rerun the same failing command or request.
Avoid destructive commands, credential rotation, billing changes, or security relaxations without a rollback plan.

What this error means

CrashLoopBackOff | kubelet eviction node memory pressure/disk pressure | OOMKilled (Exit Code 137) is a Kubernetes failure pattern reported for developers trying to debug kubernetes crashloopbackoff pod with empty logs, distinguish between application crashes vs node resource eviction (oom/memory pressure). Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.

Why this happens

Comprehensive June 2026 guide identifies 7 root causes of CrashLoopBackOff including liveness probe failures, missing ConfigMaps, wrong volume permissions, and node-level pressure evictions. Key insight: empty logs often indicate node eviction (not app crash). Distinct actionable workflow with kubectl --previous logs, dmesg OOM check, and securityContext.fsGroup fix. Not a duplicate of generic K8s tutorials — focuses on specific diagnostic confusion that blocks production debugging. Category: Cloud Platforms per approved list.

Quick fixes

Confirm the exact error signature matches CrashLoopBackOff | kubelet eviction node memory pressure/disk pressure | OOMKilled (Exit Code 137).
Check the Kubernetes account, local tool state, and provider configuration involved in the failing workflow.
Compare the failing environment with a known working setup, then change one configuration value at a time.

Platform/tool-specific checks

Verify the command, editor, extension, or API client that produced the error.
Compare local settings with CI, deployment, or editor-level settings when the error appears in only one environment.
Avoid deleting credentials, local model data, or project settings until the failing scope is clear.

Step-by-step troubleshooting

Capture the exact error message and the command, editor action, or request that triggered it.
Check whether the failure is account/auth, quota/rate, model/provider, local runtime, or deployment configuration.
Review the source evidence below and compare it with your environment.
Apply one change at a time and rerun the smallest failing action.
Keep the working fix documented for the team or deployment environment.

How to prevent it

Keep provider/tool configuration documented.
Record non-secret diagnostics such as tool version, provider name, model name, and command path.
Add a lightweight check before CI or production workflows depend on the tool.
