In clusters using the AWS EBS CSI driver, the controller may fail to detach a volume if the associated VolumeAttachment resource has an empty `spec.nodeName`. This results in a log error and skipped detachment, which may block PVC reuse or node cleanup.
\- When deploying Grafana Loki with AWS S3 as the storage backend and specifying a custom S3 endpoint (e.g., for FIPS compliance or GovCloud regions), Loki may fail to retrieve AWS credentials via IAM Roles for Service Accounts (IRSA). This results in errors during startup or when attempting to upload index tables, preventing Loki from functioning correctly.
\- When using AWS Network Policy Agent with VPC CNI addon v1.17.1, the log message `failed to get caller` may appear frequently.
\- EKS may be able to handle steady, predictable scale, but struggles during large‑scale auto scaling events when many workloads and nodes are spinning up or down simultaneously.
