SYMPTOMS
A COM+ Application Package that contains a COM Transaction Integrator (COMTI) component occasionally stops responding while shutting down. This occurs intermittently on multi-processor servers after the Dllhost process has been automatically shut down after being idle. The load on the server has no effect on the occurrence of this problem.



CAUSE
During shutdown, the Snasii.dll encountered a race condition when trying to free a thread handle. Snasii.dll is used with Host Security Integration and, by default, is always loaded.



Service pack information
To resolve this problem, obtain the latest service pack for Microsoft Host Integration Server 2000. For more information, click the following article number to view the article in the Microsoft Knowledge Base:

Hotfix information
The English version of this hotfix has the file attributes (or later file attributes) that are listed in the following table. The dates and times for these files are listed in Coordinated Universal Time (UTC). When you view the file information, it is converted to local time. To find the difference between UTC and local time, use the Time Zone tab in the Date and Time tool in Control Panel.   Date         Time   Version      Size    File name ---  15-Aug-2002  13:30  5.0.0.900    49,424  Snasii.dll

NOTE: Because of file dependencies, the most recent fix that contains the preceding files may also contain additional files.



WORKAROUND
To work around this issue, use one of the following methods:
 * Rename the Snasii.dll file so it is not loaded. This works only if Host Security Integration is not being used.
 * Change the properties of the COM+ Application package so Dllhost is not shut down after it is idle for a specified time.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.

This problem was corrected in Microsoft Host Integration Server 2000 Service Pack 2.
