FIX: The "301" shutdown event may not be correctly logged to the event log in Windows Media Services 9 Series (888905)


The information in this article applies to:

  • Microsoft Windows Media Services 9 Series

SYMPTOMS

When the Microsoft Windows Media Services (WMS) 9 Series service is stopped in a normal manner, the service is supposed to write a "301" shutdown event to the event log. When the "301" shutdown event is written to the event log, this documents the shutdown. Typically, the event log entry is supposed to look similar to the following:

Event Type: Information
Event Source: WMServer
Event Category: Multimedia
Event ID: 301
Date: 28/10/2004
Time: 15:14:09
User: N/A
Computer: MACHINENAME
Description: The Windows Media service has stopped. For more information, see Help and Support Center at http://support.microsoft.com.

On some computers, you may not see the shutdown event consistently logged. However, the service does terminate without incident.

CAUSE

This problem is caused by a race condition in the shutdown sequence of WMS. On some computers, the main server thread is terminated before the shutdown event is successfully written to the event log.
