Diagnose and resolve Buttercup CRS pod crashes, cascading failures, and service misbehavior on Kubernetes. All pods run in namespace crs . Key services: Always start with triage. Run these three commands first: Then narrow down: High restart counts don't necessarily mean an issue is ongoing -- restarts accumulate over a pod's lifetime. Always distinguish: When many pods restart around the same time, check for a shared-dependency failure before investigating individual pods. The most common cascade: Redis goes down -> every service gets ConnectionError / ConnectionRefusedError -> mass restarts. Look for the same error across multiple --previous logs -- if they all say redis.exceptions.ConnectionError , debug Redis, not the individual services. Redis is the backbone.
