Symptoms
Consider the following scenario. You have a computer that is running Windows 7 or Windows Server 2008 R2. This computer has a third-party application installed that uses the Windows Filtering Platform (WFP) callout driver. In this scenario, you may receive an error message on a blue screen. This error message resembles the following:
STOP: 0x00000050 (parameter1, parameter2, parameter3, parameter4)
PAGE_FAULT_IN_NONPAGED_AREANotes
-
The parameters in this Stop error message may vary, depending on the configuration of the computer.
-
Not all "Stop 0x00000050" error messages are caused by this problem.
-
Cause
This problem occurs because of an error in the TCPIP.sys system driver. When the WFP callout driver calls the FwpsReleaseClassifyHandle0 function to free up some system resources, the Stop error occurs.
