TITLE   :XADM: Information Store Crash in FreePadrlist:padrlist
PRODUCT :Microsoft Exchange
PROD/VER:winnt:5.5
OPER/SYS:
KEYWORDS:exc55 EXC55SP3Fix

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

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


SYMPTOMS
========

The Microsoft Exchange Server information store may end unexpectedly (crash)
while processing inbound Simple Mail Transfer Protocol (SMTP) messages.

CAUSE
=====

While processing attachments contained within another message, the running
thread overwrites its stack by 1 byte. Ultimately, a false (overwritten) address
is used as a return address, causing Store.exe to violate access.

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
Microsoft Knowledge Base:

   Q191014 XGEN: How to Obtain the Latest Exchange Server 5.5 Service Pack
