You have Symantec Endpoint Protection 11.x (SEP) or Symantec AntiVirus Corporate Edition 10.x (SAV) installed on a Windows Server or Workstation. When the system is under heavy load, it may crash with a so called  Blue Screen  of Death (BSOD), and the reported BugCheck is C2, {44, 0, 80000000, 0}.


If the system is not configured to create a memory dump file, you may see the following Events in the Windows Event Viewer:

System Error 1003 Error code 000000c2, parameter1 00000044, parameter2 00000000, parameter3 80000000, parameter4 00000000

If you have a memory dump file and the ability to analyze it with Debugging Tools for Windows, you may see data similar to the following:


The current thread is making a bad pool request.  Typically this is at a bad IRQL level or double freeing the same allocation, etc.


Arg1: 00000044, Attempt to free a non-allocated nonpaged pool address

Arg2: 00000000, Starting address

Arg3: 80000000, (reserved)

Arg4: 00000000, 0

 Limited Paged Pool Resources in combination with an identified AVEngine component may cause these crashes when the system is under heavy load.


The AVEngine with the fix included was released for SEP 11 on December 9. Definitions dated 20101208.036 or later contain this updated AVEngine.

These AVEngine updates occur periodically - typically once a quarter - and are distributed automatically via a Virus Definition update. No other specific action is required.

To identify if your SEP or SAV client has been updated automatically  to the AVEngine in question, you could verify the file version of the following files:


32-bit AVEngine File Versions
NAVEX15.SYS 20101.3.0.103
NAVENG32.DLL 20101.3.0.103


64-bit AVEngine File Versions

ex64.sys 20101.3.0.103
eng64.sys 20101.3.0.103

The Definitions for SAV 10 are expected to be available on December 10. 

As a temporary workaround, you could apply the workaround as documented on to modify the system's Paged Pool Memory settings.
