• What is the cause and solution for SAP error message ITS118 - Available virtual memory ?

  The SAP error message ITS118, which refers to "Available virtual memory," typically indicates that the system is running low on virtual memory resources. This can lead to performance issues or even system crashes if not addressed. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Insufficient Virtual Memory: The system may not have enough virtual memory allocated to handle the current workload.
  Memory Leaks: Applications or processes may be consuming more memory than they should, leading to exhaustion of available memory.
  Configuration Issues: The system may not be configured optimally for the workload it is handling.
  High Load: A sudden increase in user load or background processes can lead to high memory consumption.
  Operating System Limits: The underlying operating system may have limits on the amount of virtual memory that can be allocated.
  
  Solutions:
  
  
  Increase Virtual Memory:
  
  On Windows, you can increase the paging file size through System Properties > Advanced > Performance Settings > Advanced > Virtual Memory.
  On Unix/Linux systems, you may need to adjust swap space or configure system parameters.
  
  
  
  Optimize SAP Configuration:
  
  Review and optimize the SAP instance profile parameters related to memory management (e.g., abap/heap_area_total, abap/heap_area_dia, etc.).
  Ensure that the parameters are set according to the recommended values for your system's workload.
  
  
  
  Monitor and Manage Processes:
  
  Use transaction codes like ST02 (Tune Summary) and ST03 (Workload Analysis) to monitor memory usage and identify any processes that are consuming excessive memory.
  Consider terminating or optimizing long-running or memory-intensive processes.
  
  
  
  Check for Memory Leaks:
  
  Investigate if there are any custom programs or third-party add-ons that may be causing memory leaks. Debugging and analyzing the code may be necessary.
  
  
  
  System Restart:
  
  In some cases, a system restart may help clear memory and resolve temporary issues.
  
  
  
  Upgrade Hardware:
  
  If the system consistently runs low on memory, consider upgrading the server hardware to provide more RAM.
  
  
  
  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 properly. Familiarize yourself with the different memory areas (e.g., heap memory, buffer memory).
  Performance Monitoring Tools: Utilize SAP's performance monitoring tools to keep an eye on memory usage and system performance.
  Documentation: Refer to SAP documentation for best practices on memory management and configuration settings.
  
  If the problem persists after trying these solutions, it may be beneficial to contact SAP support for further assistance.
