Component : Network Infrastructure - Frontend Services - use subcomponents (see note 1322184)

Summary :
This SAP Note details a termination issue between the application server and SAP GUI. The connection is lost due to network interference, frontend closure, or SAP GUI process termination without logoff. Error logs in 'dev_disp' and system logs mention connection resets. Reasons include unexpected frontend host shutdowns and network disruptions. Diagnosing involves checking exit messages on frontend GUI or trace files for network errors. Corrective actions should focus on identifying root causes through frontend notifications or dispatcher trace logs in ‘dev_disp’, which provide session and transaction details for forensic analysis.
