A financial services company runs a critical trading application on Kubernetes. The application is deployed as a Deployment with 3 replicas. Each pod exposes metrics on port 8080 and uses a ConfigMap to load configuration. Recently, after a configuration change via a ConfigMap update, two of the three pods started crashing with an out-of-memory (OOM) error, while the third pod continues to run fine. The team verified that the ConfigMap was updated correctly and that the application code did not change. The pods have resource limits set: memory limit of 512Mi and request of 256Mi. The application's memory usage before the change was around 200Mi. The new configuration increases the in-memory cache size. The team suspects the issue is related to the configuration change. What is the best course of action?
