Smart SAP Assistant

• What is the cause and solution for SAP error message 14090 - Debug proxy already running ?

  The SAP error message "14090: Debug proxy already running" typically occurs when you attempt to start a debug session in the SAP system, but a previous debug session is still active. This can happen if a previous debugging session was not properly terminated or if there are multiple attempts to start debugging simultaneously.
  Cause:
  
  Active Debug Session: A debug session is already running for the same user or in the same context.
  Improper Termination: The previous debug session was not closed properly, possibly due to a crash or forced termination.
  Multiple Instances: Attempting to start debugging from multiple sessions or instances of the SAP GUI.
  
  Solution:
  
  
  Terminate Existing Debug Session:
  
  Check if there is an active debug session. You can do this by using transaction SM50 (Process Overview) to see if there are any active processes related to your user.
  If you find an active debug session, you can terminate it from the SM50 transaction by selecting the process and choosing the "End Process" option.
  
  
  
  Log Off and Log Back In:
  
  Sometimes, simply logging off from the SAP system and logging back in can clear any lingering debug sessions.
  
  
  
  Check for Multiple Sessions:
  
  Ensure that you are not trying to start a debug session from multiple SAP GUI instances. Close any additional instances that may be running.
  
  
  
  Restart SAP GUI:
  
  Close the SAP GUI completely and restart it. This can help reset any lingering connections or sessions.
  
  
  
  System Restart (if applicable):
  
  If the issue persists and you have the necessary permissions, consider restarting the application server. However, this should be done with caution and typically requires coordination with your SAP Basis team.
