XADM: Store Crash When IMAP Append Is Aborted on 100 MB Network (195741)

The information in this article applies to:

Microsoft Exchange Server 5.5

This article was previously published under Q195741

SYMPTOMS

If an Internet Message Access Protocol version 4 (IMAP4) Append command from a client is aborted on a 100-MB network without waiting for the Server Response, an access violation error may occur in the information store.

CAUSE

The information store loses a connection endpoint, and cleans up properly. However, the Append function in IMAP does not know this, and tries to access a member function of the encapsulating net connection class. Because that instance is not valid, the information store gets an access violation.

RESOLUTION

To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For more information, please see the following article in the Microsoft Knowledge Base:

191014 XGEN: How to Obtain the Latest Exchange Server 5.5 Service Pack

The English version of this fix should have the following file attributes or later:

Component: Information Store

   File Name    Version
   -----------------------
   Gapi32.dll   5.5.2445.0
   Mdbmsg.dll   5.5.2445.0
   Store.exe    5.5.2445.0

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.5.
