• What is the cause and solution for SAP error message ITS126 - Total quota peak paged pool usage of all AGate processes of this host ?

  The SAP error message ITS126 indicates that the total quota peak paged pool usage of all AGate processes on the host has exceeded the allowed limit. This is typically related to memory management issues within the SAP Internet Transaction Server (ITS) environment.
  Cause:
  
  
  Memory Limit Exceeded: The error usually occurs when the total memory allocated for the AGate processes exceeds the configured limits. This can happen due to:
  
  High traffic or load on the server.
  Inefficient memory usage by the AGate processes.
  Insufficient system resources allocated to the SAP system.
  
  
  
  Configuration Issues: The configuration settings for memory allocation may not be optimized for the current workload.
  
  
  Resource Leaks: There may be memory leaks in the application or in the AGate processes that lead to increased memory consumption over time.
  
  
  Solution:
  
  
  Increase Memory Quota:
  
  You can increase the memory quota for the AGate processes. This can be done by adjusting the parameters in the SAP kernel or the operating system settings.
  Check the max_paged_pool_size setting in the Windows registry if you are running on a Windows server.
  
  
  
  Optimize AGate Configuration:
  
  Review and optimize the configuration settings for AGate processes. This includes adjusting parameters related to memory allocation and process limits.
  Ensure that the max_connections and max_sessions parameters are set appropriately based on the expected load.
  
  
  
  Monitor and Analyze Usage:
  
  Use monitoring tools to analyze memory usage patterns and identify any processes that are consuming excessive memory.
  Check for any long-running transactions or sessions that may be holding onto resources unnecessarily.
  
  
  
  Restart AGate Processes:
  
  If the memory usage is critically high, consider restarting the AGate processes to free up memory. However, this should be done during a maintenance window to avoid disrupting users.
  
  
  
  System Resources:
  
  Ensure that the server has adequate physical memory and resources to handle the load. If necessary, consider upgrading the hardware.
  
  
  
  Patch and Update:
  
  Ensure that your SAP system and its components are up to date with the latest patches and updates, as these may contain fixes for memory management issues.
