FIX: Active Script Host Stops Responding in Pdm.dll

This article has been archived. It is offered "as is" and will no longer be updated.
When you run scripts continuously in many threads in an active script host, the application may deadlock on critical sections in the Pdm.dll file. When the application is in the deadlock state, the CPU utilization for the application that appears in Task Manager will be close to 0 percent. This problem occurs more frequently in multiprocessor computers.
