• What is the cause and solution for SAP error message VIRT195 - Guaranteed Memory Consumed ?

  The SAP error message VIRT195: Guaranteed Memory Consumed typically indicates that the SAP system has reached a limit on the guaranteed memory allocation for a particular work process. This can happen in environments where memory management is tightly controlled, and it often relates to the configuration of the SAP instance or the underlying operating system.
  Cause:
  
  Memory Allocation Limits: The SAP system has a defined limit for memory allocation per work process. If the processes exceed this limit, the error is triggered.
  High Workload: A sudden increase in workload or inefficient processing can lead to excessive memory consumption.
  Configuration Issues: Incorrect configuration of the instance profile parameters related to memory management can lead to this error.
  Memory Leaks: Applications or custom code that do not release memory properly can lead to increased memory consumption over time.
  
  Solution:
  
  
  Increase Memory Limits:
  
  Review and adjust the instance profile parameters related to memory allocation. Key parameters include:
  
  abap/heap_area_dia
  abap/heap_area_nondia
  abap/heap_area_total
  
  
  Increase these values to allow more memory for the work processes.
  
  
  
  Optimize Workload:
  
  Analyze the workload on the system. Identify and optimize long-running or resource-intensive transactions.
  Consider scheduling heavy jobs during off-peak hours to balance the load.
  
  
  
  Monitor Memory Usage:
  
  Use transaction codes like ST02 (Tune Summary) and ST03 (Workload Analysis) to monitor memory usage and identify potential bottlenecks.
  Check for memory leaks in custom code or third-party applications.
  
  
  
  Review and Optimize Code:
  
  If custom ABAP programs are causing high memory usage, review and optimize them to ensure they are efficient and do not consume excessive memory.
  
  
  
  System Restart:
  
  In some cases, a system restart may help clear memory and resolve temporary issues.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional guidance.
  
  
  
  Related Information:
  
  SAP Memory Management: Understanding how SAP manages memory can help in configuring the system appropriately. Familiarize yourself with the different types of memory (heap memory, shared memory, etc.) and their configurations.
  Performance Tuning: Regular performance tuning and monitoring can help prevent memory-related issues from arising.
  SAP Basis Team: Collaborate with your SAP Basis team to ensure that the system is configured optimally and that any changes made are in line with best practices.
  
  If the problem persists after trying the above solutions, it may be necessary to engage SAP support for further assistance.
