Symptoms

Consider the following scenario:

  • You have a computer that is running one of the following operating systems:

    • Windows Vista

    • Windows Server 2008

    • Windows 7

    • Windows Server 2008 R2

  • You install a storage controller that uses the Storport.sys driver on the computer.

    For example, you install the Hitachi PCI Fibre Channel adapter or the QLogic Fibre Channel adapter on the computer.

  • You disable and then enable the storage controller in Device Manager frequently.

In this scenario, nonpaged pool usage increases when you disable and enable the storage controller. If you trace the nonpaged pool usage or debug the computer, the trace or debug information indicates that the nonpaged pool usage that have the following tags keeps increasing:

  • PlRB

  • Dict

  • RaRm

  • RaDS

When the nonpaged pool memory is exhausted, the server may stop responding, crash, or encounter function failure.

Cause

This issue occurs because the StorPort.sys driver does not release some of its pool allocations when the storage controller is disabled.
