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

View products that this article applies to.

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.
