• What is the cause and solution for SAP error message /UI5/APP_API134 - Full mode causes high system load, only use it in exceptional cases ?

  The SAP error message /UI5/APP_API134 Full mode causes high system load, only use it in exceptional cases is related to the SAP Fiori/UI5 applications and indicates that the application is running in "full mode," which can lead to increased system load and performance issues. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Full Mode Usage: The application is being executed in full mode, which is typically used for debugging or development purposes. This mode loads all components and resources, which can significantly increase the load on the system.
  High Resource Consumption: Full mode can consume more memory and processing power, leading to performance degradation, especially in production environments.
  Configuration Settings: The system may be configured to default to full mode for certain applications or users, which is not ideal for regular operations.
  
  Solution:
  
  Switch to Normal Mode: If you are running the application in full mode, switch to normal mode. This can usually be done by changing the application settings or parameters in the launchpad or application configuration.
  Check User Settings: Ensure that user-specific settings do not default to full mode. This can often be configured in the user profile or settings.
  Performance Monitoring: Monitor system performance and resource usage. If full mode is necessary for certain tasks, consider scheduling these tasks during off-peak hours to minimize impact.
  Review Application Code: If you are a developer, review the application code to ensure that it is optimized for performance and does not unnecessarily invoke full mode.
  Consult Documentation: Refer to SAP documentation for specific applications to understand the implications of running in full mode and any recommended practices.
  
  Related Information:
  
  SAP Notes and Documentation: Check SAP Notes related to UI5 and Fiori applications for any updates or patches that may address performance issues.
  SAP Community: Engage with the SAP Community for insights and experiences from other users who may have encountered similar issues.
  Performance Tuning: Consider general performance tuning practices for SAP systems, such as optimizing database queries, adjusting server resources, and ensuring proper caching mechanisms are in place.
  
  By addressing the use of full mode and ensuring that applications run in the appropriate mode for their context, you can mitigate the high system load and improve overall performance.
