The Active Directory Application Mode service may crash if the Active Directory Application Mode instance database is of a large scale on a computer that is running Windows Server 2003 SP2

The Active Directory Application Mode service may crash on a computer that is running Windows Server 2003 Service Pack 2 (SP2) and that has a large scale Active Directory Application Mode instance database. An example of a large scale database is a database that is over 10 gigabytes (GB). This issue occurs when a Lightweight Directory Access Protocol (LDAP) query is handled.

Additionally, when the issue occurs, the following event log is added to the related Active Directory Application Mode event log:

Event Type: Warning
Event Source: ADAM <instance name> General
Event Category: Internal Processing
Event ID: 1173
Description:
Internal event: Active Directory has encountered the following exception and associated parameters.

Exception: c0000005
Parameter: 0

Additional Data
Error value: 7c82fc58
Internal ID: 0

This problem occurs because the Active Directory Application Mode service manages search duplicate buffers incorrectly. This behavior causes the Active Directory Application Mode service to crash.
