COMTI May Stop Responding on Multi-Processor Systems (327814)



The information in this article applies to:

  • Microsoft Host Integration Server 2000

This article was previously published under Q327814

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.

RESOLUTION

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:

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 "Applies to" section.

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