COM+ Application Stops Responding on Idle Shutdown If You Configure Application as Queued and ListeningArticle ID: 319007 - View products that this article applies to. This article was previously published under Q319007 SYMPTOMS
When COM+ tries to shut down an application because the idle time limit has been reached, the Dllhost.exe process may stop responding (hang) and may consume 100 percent of the processor (CPU). This problem occurs only if you configure the application as Queued and Listening.
CAUSE
When the shutdown process is initiated, the process acquires the lock for the threading pool first and then waits for the threads in the pool to exit. At the same time, the queued component (QC) thread (which is also member of the pool) tries to acquire the same lock in a tight loop. As a result, this situation causes both a deadlock and 100 percent CPU utilization.
RESOLUTION
To resolve this problem, obtain Microsoft COM+ Hotfix Rollup 19.
