The storport.sys driver leaks nonpaged pool memory when volumes are scanned, mounted, or dismounted in Windows Server 2008 and Windows Vista
Consider the following scenario:
- You have some high-performance storage devices that are installed on a computer that is running Windows Server 2008 or Windows Vista. For example, you have a host-based RAID or a fiber-channel adapter installed.
- Some applications or services, such as Microsoft iSCSI Software Target, frequently scan, mount, or unmount volumes on this computer.
In this scenario, the nonpaged pool memory leaks continuously. Therefore, the performance of the computer begins to decrease. Eventually, all nonpaged pool memory is used, and the computer may crash. Or, the computer may automatically restart with a Stop error code.
