A computer that is running Windows Server 2008 SP2 or Windows Vista SP2 stops responding when an application uses the NTFS sparse files

Symptoms

When an application uses the NT file system (NTFS) sparse files on a computer that is running Windows Server 2008 Service Pack 2 (SP2) or Windows Vista Service Pack 2 (SP2), the computer stops responding.



When this problem occurs, all I/O operations are blocked. Therefore, you must restart the computer.

Cause

This problem occurs because of a timing issue that occurs in the Windows NT File System driver (Ntfs.sys). This issue causes a deadlock.
