Intermittent Access Violations Occur with Abnormal Disconnect

The information in this article applies to:

• Microsoft Commercial Internet System, version 1.0

SYMPTOMS

The server may crash intermittently when users disconnect abnormally. An access violation may occur frequently during query and infrequently during channel join operations. This happens because the user who is performing the operation is disconnected. The user object gets released and is then written to by the thread processing the query or join.

RESOLUTION

The Chatsvc.dll file has been modified to correct the problem of the user object being incorrectly deleted during clean up of a socket close. Upgrade with Service Pack 1 (SP1) for MCIS v1.0. This will update the Chatsvc.dll file, and correct the problem.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Commercial Internet System, version 1.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
