SYMPTOMS
Under certain conditions, a synchronization object (such as a mutex object) may be abandoned. However, threads that are waiting for the object are not released. This behavior may cause a process to stop responding when the threads of the process wait on a synchronization object.



CAUSE
A race condition may occur between the creation and deletion of a named synchronization object. If a thread creates a named synchronization object at the same time as another thread deletes the same named synchronization object, a new handle is created although the old object still exists. Both threads wait for different synchronization objects instead of waiting for the same named object that they expected to use.
