SYMPTOMS

A Microsoft Windows Server 2003-based computer stops responding when an application frequently schedules threads. This problem usually occurs if the application repeatedly uses one or more of the following functions:

  • SetThreadAffinityMask
  • SetThreadIdealProcessor
  • SetProcessAffinityMask


CAUSE

This problem occurs because of a synchronization issue in the thread scheduling code. If an application changes the affinity of a thread while the system is using the affinity, the affinity may not be synchronized correctly. This situation may cause an endless loop to occur.
