"0x00000004E" Stop error occurs when some users try to access shared files in Windows Server 2008 or in Windows Vista

Symptoms

Consider the following scenario:
  • You share some files on a computer that is running Windows Server 2008 or Windows Vista.
  • Some users try to access these shared files.
In this scenario, the computer may restart unexpectedly. Additionally, you receive a Stop error that resembles the following:
STOP 0x0000004E (0x0000009A,parameter2, parameter3, parameter4 )PFN_LIST_CORRUPT
Notes
  • The first parameter, 0x0000009A, indicates that a driver tried to free a page that is still locked for I/O.
  • The parameters in the Stop error message vary, depending on the configuration of the computer.
  • Not all "0x0000004E" Stop errors are caused by this problem.

Cause

A thread of the Redirected Driver Buffering SubSystem (Rdbss.sys) driver is completing an I/O request packet (IRP). However, some pages used by the IRP are still locked. Therefore, you receive the Stop error message.
