Answer: This error occurs when the Service Mapping ML Intelligence engine times out while trying to generate application/service mapping suggestions. The issue is not related to Discovery or pattern execution directly but to the ML training pipeline not completing in time. Troubleshooting Steps: Confirm the ML Intelligence for Service Mapping plugin is installed and active. Review System Properties for ML Intelligence: sn_ml.service_mapping.enabled should be set to true. Check System Logs for the message training request timeou.e. Validate that the Application Suggestion job runs without errors in Step 5 of KB963421. If Step 5 isn’t configured, Step 6 will fail.
