SYMPTOMS
If you install Citrix Metaframe server-based software on your computer running Windows NT 4.0, Terminal Server Edition, the computer may crash and either of the following error messages may be displayed on a blue screen:


 * STOP 0000000a : 39b880ce 00000002 00000000 801335d8

IRQL_NOT_LESS_OR_EQUAL
 * STOP 0000004e : 00000007 00000e32 00000001 00000000

NOTE: The parameters may be different, depending on your system configuration.



CAUSE
In certain conditions, Metaframe's kernel mode driver (Cdm.sys) dereferences physical pages that are not referenced. This creates a condition where the reference count of a physical page is 0, but the share count is still 1 (the page is still on some lists).

To preserve system integrity, Terminal Server Edition is set to crash when these conditions are present.



RESOLUTION
To resolve this issue, contact Citrix to obtain a fix for this problem. The latest updates to the Metaframe Cdm.sys driver should also contain this fix.
