+# Runbook: JVM_OOM (`runbook://runtime/jvm-oom`)
+
+## Symptoms
+
+- Container exits with code 137 (ExitOnOutOfMemoryError triggered)
+- Structured log entry with `error.code=JVM_OOM` before exit
+
+## Diagnosis
+
+- Check heap dump if `-XX:HeapDumpOnOutOfMemoryError` is configured
+- Review memory usage trends before crash
+- Check for memory leaks: large cache growth, unbounded lists, session accumulation
+
+## Action
+
+- Restart container immediately (k8s will auto-restart with liveness probe)
+- If recurring: increase heap `-Xmx` or fix memory leak
+
+## Escalation
+
+- P1: immediate if multiple pods crashing simultaneously
+- Page SRE / infra team for heap analysis
