  • Question

  • I ran the FSCT 1.2. In the result summary , I am seeing the Available physical memory in negative value. Then in the server resources there is available memory. So what the negative value indicates ?

    In the above server resources, memory is still available. How it is calculated and why it is in negative value. 
    The same test if i repeat i see a positive value. This tool gives everytime + and - ve value which is unreliable
