DOCUMENT:Q256467 01-JUN-2001 [exchange] TITLE :XADM: Information Store Doesn't Log Message in Event Log PRODUCT :Microsoft Exchange PROD/VER::5.5 OPER/SYS: KEYWORDS:exc55 kbExchange550preSP4fix kbExchange550sp4Fix kbgraphxlinkcritical ====================================================================== ------------------------------------------------------------------------------- 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.
