Summary :
The SAP Note addresses the issue where IGS becomes unresponsive with specific errors logged in the trace files, such as "NiListen on port 40080 failed" and "NiBufListen failed". The root cause is linked to port conflicts due to ports being occupied by stale IGS processes or other programs. The solution involves ensuring all IGS processes are terminated, verifying that the required ports are free using tools like 'netstat', and restarting IGS. It’s crucial to manage starting and stopping IGS via the SAP Start Framework to prevent port conflicts and ensure correct IGS functionality. Steps are also provided to check the health of IGS after troubleshooting.
