• What is the cause and solution for SAP error message CSM_VMC035 - Average Memory Consumption per VM ?

  The SAP error message CSM_VMC035, which pertains to "Average Memory Consumption per VM," typically indicates that the average memory consumption of virtual machines (VMs) in your SAP landscape is exceeding a predefined threshold. This can lead to performance issues and may affect the overall stability of your SAP applications.
  Cause:
  
  High Memory Usage: The VMs may be consuming more memory than expected due to high workloads, inefficient applications, or memory leaks.
  Configuration Issues: The VMs may not be optimally configured for the workloads they are handling, leading to excessive memory consumption.
  Resource Contention: If multiple VMs are competing for limited resources on the host, it can lead to increased memory usage.
  Inadequate Hardware: The underlying hardware may not have sufficient resources to support the memory demands of the VMs.
  
  Solution:
  
  Monitor Memory Usage: Use monitoring tools to analyze memory consumption patterns and identify which VMs are consuming excessive memory.
  Optimize VM Configuration: Review and adjust the memory allocation for each VM based on their actual usage and requirements. Ensure that the VMs are not over-provisioned.
  Scale Resources: If the workload has increased, consider scaling up the resources (CPU, memory) of the VMs or adding more VMs to distribute the load.
  Review Applications: Check the applications running on the VMs for inefficiencies or memory leaks. Optimize or update them as necessary.
  Host Resource Management: Ensure that the host machine has adequate resources and is not overloaded. Consider upgrading the hardware if necessary.
  Use SAP Notes: Check for any relevant SAP Notes that may provide specific guidance or patches related to memory management in your SAP environment.
  
  Related Information:
  
  SAP Basis Administration: Understanding how to manage and configure SAP systems and their underlying infrastructure is crucial.
  Performance Tuning: Familiarize yourself with performance tuning techniques for both SAP applications and the underlying operating systems.
  SAP Community and Support: Engage with the SAP Community or SAP Support for insights and solutions from other users who may have faced similar issues.
  Documentation: Refer to SAP documentation for guidelines on memory management and best practices for configuring VMs in an SAP environment.
  
  By addressing the underlying causes and implementing the suggested solutions, you can mitigate the CSM_VMC035 error and improve the performance of your SAP landscape.
