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

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


SYMPTOMS
========

The Exchange Server information store may not log application events, or the
information store may stop responding with an access violation. This issue
occurs only if the information store diagnostics Transport Delivering option is
set to medium or higher and you receive a message that contains many recipients.

CAUSE
=====

This issue can occur if the information store attempts to log an application
event and submits more than 32 kilobytes (KB) of data to the Microsoft Windows
NT ReportEvent() application programming interface (API). In Windows NT 4.0, if
more than 32 KB of data is passed to this API, the API may stop responding and
may cause unpredictable behavior such as a crash, or an inability to log
subsequent events.


Any attempt to submit more than 32 KB of data to the ReportEvent() API is an
error, and the attempt to log the event does not work (which results in the
absence of this diagnostic event).

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Exchange Server 5.5.
