# A Kubernetes container shows reason OOMKilled with exit code 137. What does the exit code 137 tell you?

Kubernetes, Easy (Beginner), Troubleshooting. https://k8wiz.com/uquiz/a-kubernetes-container-shows-reason-oomkilled-with-exit-code-137-what-does-the-exit-code-137-tell-you

- A. The process was killed by SIGTERM, signal 15
- B. The process was killed by SIGKILL, signal 9
- C. The process was killed by SIGSEGV, signal 11
- D. The process was killed by SIGABRT, signal 6

**Answer:** The process was killed by SIGKILL, signal 9

**Explanation:** A process killed by a signal reports an exit code of 128 plus the signal number, and 128 + 9 = 137. The kernel OOM killer uses SIGKILL, which can't be caught. SIGTERM would give 143, and a SIGKILL can also come from the kubelet after a grace period runs out, so check the OOMKilled reason too.
