Computer stops responding when you run an application that uses the Windows Filtering Platform API in Windows 7, Windows Server 2008 R2, Windows Server 2008, or Windows Vista

Not sure if this is the right fix? We've added this issue to our memory dump diagnostic which can confirm.

Symptoms

Assume that you run an application that uses the Windows Filtering Platform API for several minutes on a computer that is running one of the following operating systems:

  • Windows 7

  • Windows Server 2008 R2

  • Windows Server 2008

  • Windows Vista

In this situation, the computer stops responding and there is no network activity. To recover from this issue, you have to perform a hard restart.

Cause

This issue occurs because the FwpsStreamInjectAsync0 function causes the interrupt request level (IRQL) to leak.
