• What is the cause and solution for SAP error message VIRT173 - StealTime ?

  The SAP error message VIRT173, which refers to "StealTime," typically indicates that there is a performance issue related to the virtual memory management of the SAP system. This error is often associated with the system's inability to efficiently manage resources, leading to increased "steal time," which is the time a virtual CPU spends waiting for physical CPU resources due to contention.
  Causes of VIRT173 StealTime
  
  Resource Contention: The virtual machine (VM) may be competing for CPU resources with other VMs on the same physical host.
  Insufficient CPU Allocation: The SAP system may not have enough virtual CPUs allocated to handle the workload effectively.
  Overprovisioning: If too many VMs are running on the same physical server, it can lead to resource contention and increased steal time.
  Hypervisor Configuration: Misconfigurations in the hypervisor settings can lead to inefficient resource allocation.
  High Load: A sudden spike in workload can lead to increased CPU demand, resulting in higher steal time.
