Symptoms include exceptions of memory exhaustion on IoT Edge Hub modules, downlink devices failing to connect, or devices failing to send telemetry messages after several hours. IoT Edge detects situations when the device appears to be redeployed in the cloud by monitoring IoT Edges native IoT Hub connections for specific errors.
