The memory usage of the Svchost.exe process for Windows Deployment Services keeps increasing after you install hotfix 960489 or install Windows Server 2008 SP2

Consider the following scenario:

• You install the Windows Deployment Services server role on a computer that is running Windows Server 2008.
• On this computer, you install the hotfix 960489 or install the Windows Server 2008 Service Pack 2 (SP2).

In this scenario, the Private Bytes counter of the Windows Deployment Services keeps increasing. This behavior causes a Svchost.exe process to keep increasing its memory consumption.

After the issue lasts for a long time, the computer experiences a low memory resource situation. Therefore, the applications or services that are running on the computer may crash or may encounter other function failures.
