Symptoms

A computer that is running Windows 8.1, Windows Server 2012 R2, Windows 7 Service Pack 1 (SP1), Windows Server 2008 R2 SP1 crashes. Additionally, you receive a Stop error message that resembles the following:

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

Notes

  • This Stop error describes an UNEXPECTED_KERNEL_MODE_TRAP issue.

  • The parameters in this Stop error message vary, depending on the configuration of the computer.

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

Cause

This issue is caused by stack exhaustion that occurs when the computer sends and receives Transmission Control Protocol (TCP) or Server Message Block (SMB) data. Stack exhaustion occurs because the thread on which the TCP and SMB data is received and sent does not have sufficient stack space to complete the call.
