On This Page

SUMMARY

Your Windows Server 2003-based, Windows XP-based, or Windows 2000-based computer may generate one of the following error messages on a blue screen:

Message 1
STOP: 0x0000003F (0xA,0xB,0xC,0xD) NO_MORE_SYSTEM_PTES
Message 2
STOP: 0x000000D8 (0xW,0xX,0xY,0xZ) DRIVER_USED_EXCESSIVE_PTES
This article describes how to troubleshoot these error messages.

MORE INFORMATION

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

"NO_MORE_SYSTEM_PTES" error message

This error message is usually caused by a driver that is not cleaning up properly. In the "STOP: 0x0000003F" sample error message listed earlier in this article, the parameters may vary depending on your system configuration, and they have the following meaning:
0xA - Page Table Entry (PTE) type: 0 = system expansion, 1 = non-paged pool expansion
0xB - Requested size
0xC - Total free system PTEs
0xD - Total system PTEs
Windows includes a registry value that you can use to save stack traces so that you can identify the driver that is not cleaning up properly. Use Registry Editor (Regedt32.exe) to view the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
Modify the following registry value, and then restart your computer:
Value Name: TrackPtes
Value Type: REG_DWORD
Value Data: 1
Radix: Hex
Note This is the only way to locate the driver.

"DRIVER_USED_EXCESSIVE_PTES" error message

This error message usually occurs if your computer runs out of PTEs. In the "STOP: 0x000000D8" sample error message listed earlier in this article, the parameters may vary depending on your system configuration, and they have the following meaning:
  • 0xW - If this parameter has a non-null value, it contains the name of the driver that is causing the error message. Whenever possible, the driver name is displayed in Unicode format and saved in KiBugCheckDriver.
  • 0xX - If the 0xW parameter has a non-null value, then this parameter contains the number of PTEs used by the driver that is causing the error message, and the calling stack shows the name of the driver that generated the error message.
  • 0xY - Total free system PTEs.
  • 0xZ - Total system PTEs.
Correcting the driver that is causing the error message or increasing the number of PTEs usually corrects this issue.
