FIX: COMTI components that are configured for object pooling may cause 100% CPU usage (829199)


The information in this article applies to:

  • Microsoft Host Integration Server 2000
  • Microsoft Host Integration Server 2000 SP1

SYMPTOMS

In Microsoft Host Integration Server 2000, Microsoft COM Transaction Integrator (COMTI) components may cause 100 percent CPU usage by the Microsoft COM+ application package that houses the components if object pooling is enabled. When 100 percent CPU usage occurs, you must shut down the COM+ application package to recover.

CAUSE

This intermittent problem may be caused by a timing issue in the COMTI runtime.

WORKAROUND

To work around this problem, shut down and then restart the COM+ application package. To do this:
  1. Click Start, click Settings, and then click Control Panel
  2. Double-click Administrative Tools.
  3. Double-click Component Services.
  4. In the left pane, expand Component Services, expand Computers, and then expand My Computer.
  5. Expand COM+ Applications.
  6. Right-click the application to be shutdown, and then click Shut down.
  7. After you shut down the application, right-click the application, and then click Start.
  8. Close the Component Services snap-in.
