    Spec KB: Third party applications can exhaust Windows kernel memory and result in Spectrum performance problems and crashes


    Description (truncated):

    Windows operating systems use two finite memory pools for kernel components, based on the amount of physical memory on the machine and the architecture of the Windows version. These are the paged pool, which can be paged out to disk if physical memory is low, and the much smaller non-paged pool (NPP), which guarantees that memory allocated will remain in physical memory. Once non-paged memory has been allocated it cannot be freed. For more information on the Windows kernel address space, see the references below.
    What does this have to do with Spectrum? The SpectroSERVER and Archive Manager can be indirectly impacted when non-paged pool memory is exhausted...
