On a Microsoft Windows Server 2003-based computer, you receive the following Stop error message:
Stop 0x00000020 (0x00000000, 0x0000fffc, 0x00000000, 0x00000001)
KERNEL_APC_PENDING_DURING_EXIT
The four parameters in the error message vary.
Additionally, the computer restarts automatically. After this problem occurs, an event that resembles the following 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: Computer
Description:
The computer has rebooted from a bugcheck. The bugcheck was: 0x00000020 (0x00000000, 0x0000fffc, 0x00000000, 0x00000001). A dump was saved in:
C:\WINDOWS\MEMORY.DMP.
This problem occurs because the Win32k.sys module incorrectly manages font objects. This causes an asynchronous procedure call (APC) leak. When the system detects an APC leak, the system reports the Stop error that is described in the "Symptoms" section.
