Azure Monitor (ama-metrics) high memory usage

[cin-janna]

Describe the bug
Memory on the node keeps increasing and is not released; it only drops when the pod is restarted. OOM has not occurred yet, but the resources are insufficient for other services.

Screenshots

Environment:

• Kubernetes version: v1.33.5
• Browser: chrome

Additional Info:
Clusters are in two different regions. Connected using AMPLS to the same Azure Monitor Workspace. One Azure Managed Prometheus instance connected to the workspace. Data still appears to be being collected and can be viewed fine in Prometheus.
