KB 135 (ABAP): [<Target>] 503 Service Unavailable: Server is busy
Version: 1 from 23.03.2021
If there are metric errors visible within the PowerConnect administrative console they will be visible in the following location in the user interface.
To see the error detail, please select Administrator → Metric Errors:
If you see the error “[<Target>] 503 Service Unavailable: Server is busy”, it means that the Splunk server responsible for receiving the SAP data being sent from the PowerConnect application was unable to receive the data. The data will persist in the SAP application and will be sent to the Splunk endpoint once the Splunk server is no longer too busy to receive the data.
If you continue to see this error, please reach out to your Splunk administrator to ensure that the Splunk environment is stable and performant.
