• What is the cause and solution for SAP error message ITS055 - Quota Peak Non Paged Pool Usage ?

  The SAP error message ITS055 "Quota Peak Non Paged Pool Usage" typically indicates that the system has reached a limit on the non-paged pool memory usage. This can occur in environments where there are high memory demands, particularly in systems with many concurrent users or heavy processing loads.
  Cause:
  
  High Memory Usage: The non-paged pool is a portion of memory that cannot be paged to disk and is used for kernel-mode operations. If the applications or services running on the server are consuming a lot of memory, it can lead to this error.
  Configuration Limits: The system may have configuration limits set for the non-paged pool that are too low for the current workload.
  Memory Leaks: There may be memory leaks in the applications or services that are consuming non-paged pool memory without releasing it.
  Insufficient System Resources: The server may not have enough physical memory to handle the workload, leading to increased non-paged pool usage.
  
  Solution:
  
  
  Increase Non-Paged Pool Size: If possible, increase the non-paged pool size in the system settings. This can often be done by adjusting the registry settings in Windows.
  
  Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters and modify the MaxNonPagedPoolSize value.
  Note: Be cautious when modifying the registry; incorrect changes can lead to system instability.
  
  
  
  Optimize Memory Usage: Review the applications and services running on the server to identify any that may be consuming excessive memory. Optimize or limit their usage if possible.
  
  
  Check for Memory Leaks: Use tools like Windows Performance Monitor or Debugging Tools for Windows to identify any potential memory leaks in applications.
  
  
  Upgrade Hardware: If the server is consistently running out of memory, consider upgrading the physical memory (RAM) to accommodate the workload.
  
  
  Review SAP Notes: Check the SAP Support Portal for any relevant notes or patches that may address this issue. There may be specific recommendations or fixes provided by SAP.
  
  
  Monitor System Performance: Regularly monitor the system's performance to identify trends in memory usage and take proactive measures before reaching critical limits.
  
  
  Related Information:
