SYMPTOMS

You have a .NET Framework 2.0-based Multi-AppDomain application that uses objects. These objects have finalizers that start ThreadPool methods, for example, sockets. When you run the application, you notice that the CPU usage increases significantly.

CAUSE

This problem occurs because the finalizer invokes a ThreadPool method when an application domain is unloaded. Then, the data in the thread pool is corrupted and stops working for any other application domain.
