SYMPTOMS

When a client computer logs off from a Terminal Services session, you receive a Stop error message on the terminal server. The Stop error message resembles the following:

Stop 0x000000AB (SESSION_HAS_VALID_POOL_ON_EXIT)

This problem occurs when the terminal server is running Windows Server 2003 with Service Pack 1 (SP1) or with Service Pack 2 (SP2).

When this problem occurs, other clients that are logged on to the same terminal server may also stop responding. Additionally, the following event is logged in the System log: Event Type: Information
Event Source: Save Dump
Event Category: None
Event ID: 1001
Date: Date
Time: Time
User: N/A
Computer: ComputerName
Description:
The computer has rebooted from a bugcheck. The bugcheck was: 0x000000ab (parameter1, parameter2, parameter3, parameter4). A dump was saved in: C:\WINDOWS\MEMORY.DMP.


CAUSE

This problem occurs because some objects that the Win32k.sys driver allocates from the session pool are not freed before the session ends. Defective printer drivers may cause this memory leak condition. In this case, the memory manager issues a Stop error to prevent the system from continuing in an unstable state.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

Session pool allocation is marked by a four-letter code (tag), such as "Gpat." Users can use this tag to find the leaked object. For example, some tags start with "G" for GDI objects. Other tags start with "U" for user objects.

The kernel-mode GDI code in the Win32k.sys driver calls back from the kernel mode to user-mode printer drivers. If a printer driver unexpectedly ends the thread that executes the callback, the GDI code may remain in an inconsistent state. In this case, objects may be leaked. Objects may also be leaked when the printer drivers close incorrect handles. Therefore, this problem may sometimes disappear after you update printer drivers.

This hotfix also includes all previous fixes that address "Stop 0x000000AB" issues. The investigation of the leaked tags that occur in the Win32k.sys driver is continuing. More leaked tags will be fixed when they are identified by specific cases. The following is an accumulative list of all leaked tags that this hotfix fixes:

  • Gadd
  • Gcac
  • Geto
  • Gffv
  • Gfnt
  • Ggb
  • Gglf
  • Ggls
