• What is the cause and solution for SAP error message WGDS_PROCESS674 - Daemon stopped ?

  The SAP error message WGDS_PROCESS674 Daemon stopped typically relates to issues with the SAP Gateway Daemon process. This daemon is responsible for handling communication between SAP systems and external programs or services, especially in scenarios involving RFC (Remote Function Call) or external interfaces.
  
  Cause
  
  Daemon Process Terminated Unexpectedly: The WGDS_PROCESS674 error indicates that the Gateway daemon process has stopped or crashed unexpectedly.
  Resource Issues: Insufficient system resources (CPU, memory) causing the daemon to terminate.
  Configuration Errors: Incorrect or corrupted gateway configuration parameters.
  Network Problems: Network interruptions or firewall blocking the communication ports used by the daemon.
  Software Bugs or Patch Issues: Known bugs in the SAP kernel or gateway software version.
  Operating System Issues: OS-level problems such as permission issues or process limits.
  
  
  Solution
  
  
  Check Gateway Status:
  
  Use transaction SMGW to check the status of the gateway.
  Verify if the gateway daemon is running or stopped.
  
  
  
  Restart the Gateway Daemon:
  
  On the OS level, restart the gateway daemon using SAP control commands:
  sapcontrol -nr <instance_number> -function StartGateway
  or
  sapcontrol -nr <instance_number> -function StopGateway
  sapcontrol -nr <instance_number> -function StartGateway
  
  Alternatively, restart the entire SAP instance if necessary.
  
  
  
  Check Logs:
  
  Review the gateway trace files (gw* files) located in the work directory of the SAP instance for detailed error messages.
  Check system logs for any OS-level errors.
  
  
  
  Verify Configuration:
  
  Check the gateway configuration parameters in the profile (e.g., gw/acl_mode, gw/acl_info, gw/trace, gw/reg_info).
  Ensure that the gateway is properly registered and configured.
  
  
  
  Check Network and Firewall:
  
  Ensure that the ports used by the gateway are open and not blocked by firewalls.
  Verify network connectivity between communicating systems.
  
  
  
  Apply SAP Notes / Patches:
  
  Search for relevant SAP Notes related to WGDS_PROCESS674 or gateway daemon crashes.
  Apply recommended kernel patches or gateway updates.
  
  
  
  Resource Monitoring:
  
  Monitor system resources to ensure there is enough memory and CPU available.
  Adjust system parameters if necessary.
