FIX: You experience high CPU usage and other problems when you run a .NET Framework 1.1 application

View products that this article applies to.


You run an application that you built by using the Microsoft .NET Framework version 1.1. After your application has been running for a short time, a thread in the thread pool may become corrupted.

When this problem occurs, you may experience one or more of the following problems:
  • CPU usage suddenly increases to 80 percent, and one thread in the application becomes deadlocked.
  • Another thread continues to create manual events.
  • A wait thread fires repeatedly on an AutoResetEvent event that has a Win32 native manual event under it because the wait thread is trying to process the completion.
