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.
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.
