SYMPTOMS

In a Microsoft Host Integration Server 2010 environment, you have a web application that uses Host Integration Server Transaction Integrator (TI). When the Host Integration Server TI monitoring thread is running, you notice that the W3wp.exe process consumes 100% of CPU resources. Because of this problem, the web application is unusable.

CAUSE

This problem occurs because Host Integration Server TI calls the WaitForMultipleObjects() function that uses an infinite time-out value.
