ITS129 - Details

• The SAP error message ITS129 indicates that the total quota for non-paged pool usage by all AGate processes on a host has been exceeded. This is typically related to memory management in the Windows operating system, particularly in environments where SAP Internet Transaction Server (ITS) is running.
  
  Cause:
  
  Memory Limitations: The non-paged pool is a portion of memory that cannot be paged to disk. It is used by the operating system and drivers for critical data structures. If the total usage of this pool exceeds the configured limits, it can lead to this error.
  High Load: A high number of concurrent users or transactions can increase the memory usage of AGate processes, leading to exhaustion of the non-paged pool.
  Memory Leaks: There may be memory leaks in the AGate processes or other components that are consuming more memory than expected.
  
  Configuration Issues: The system may not be optimally configured for the workload it is handling,
