Symptoms
When you log on to and log off from a Windows Server 2008-based terminal server through a Remote Desktop Protocol (RDP) connection, a memory leak may occur in the nonpaged pool memory on the Windows Server 2008-based terminal server.This issue causes a decrease in the performance of the computer. This issue may even cause the computer to stop responding (hang) if you log on and log off many times. If you use the System Performance Monitor tool (Perfmon.exe) to monitor the system memory, the tool shows a consistent increase in the nonpaged pool memory usage.
