Symptoms

Assume that you use offline files (client-side caching) on a computer that is running one of the following operating systems:

  • Windows Vista

  • Windows Server 2008

  • Windows 7

  • Windows Server 2008 R2

In this situation, the computer may crash when you try to wake the computer from Sleep (S3) mode. Additionally, you receive a Stop error message that resembles the following:

STOP: 0x0000007F (parameter1, parameter2, parameter3, parameter4)
UNEXPECTED_KERNEL_MODE_TRAP

Notes

  • Not all "0x0000007F" Stop errors are caused by this issue.

  • Parameters in this Stop error message may vary, depending on the configuration of the computer.

  • This issue occurs if no network connection is available when you wake the computer.

  • This issue may be more likely to occur if the computer has remembered connections to Distributed File System (DFS) shares that contain offline files.

Cause

This issue occurs because of a kernel stack overflow that is caused when the client-side caching driver begins a flush operation of an internal cache during the processing of an I/O request packet.

Resolution
