TITLE   :XADM: Information Store Crashes Due to Database Corruption
PRODUCT :Microsoft Exchange
PROD/VER:winnt:5.5
OPER/SYS:
KEYWORDS:EXC55SP3Fix

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Exchange Server, version 5.5 
-------------------------------------------------------------------------------


SYMPTOMS
========

An improperly handled rollback operation by the Exchange Server DB Engine causes
corruption in the database. This corruption may lead the Microsoft Exchange
Server information store to terminate unexpectedly and display an access
violation error message. If the correct Windows NT and Exchange Server debug
symbols are installed, the resulting Dr. Watson log may display a stack dump
similar to the following:

   FramePtr RetAddr Param1 Param2 Param3 Function Name

   {...})
   10816180 04560e80 1081de80 0fdabad0 1081de80 ESE!ErrRECSeparateLV+0x1c6

CAUSE
=====

When the underlying Exchange Server database engine tries to roll back the
creation of a long value (LV) tree on a table opened with exclusive access, the
database is corrupted, and the rollback is only partially successful. This
corruption will cause the information store process to terminate.

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Exchange Server
version 5.5. For additional information, please see the following article in the
