• What is the cause and solution for SAP error message GW053 - Not all connections to clients have been deleted ?

  The SAP error message GW053, which states "Not all connections to clients have been deleted," typically occurs in the context of the SAP Gateway or when dealing with RFC (Remote Function Call) connections. This error indicates that there are still active connections to the client that have not been properly closed or deleted.
  Causes:
  
  Active Sessions: There may be active sessions or connections to the client that have not been terminated.
  Network Issues: Network problems can prevent the proper closure of connections.
  Configuration Issues: Incorrect configuration settings in the SAP Gateway or RFC destinations can lead to lingering connections.
  System Load: High system load or performance issues may cause connections to hang or not close properly.
  User Lock: If a user is locked or has an active session, it may prevent the deletion of connections.
  
  Solutions:
  
  
  Check Active Connections:
  
  Use transaction code SM04 to check for active user sessions. You can log off any unnecessary sessions.
  Use transaction code SMGW to monitor and manage gateway connections. You can check for any lingering connections and delete them if necessary.
  
  
  
  Terminate Sessions:
