| Subject: | Apparent leaked task reference leading to hang on shutdown |
See the linked support ticket (#11560) for the core/exec/symbol files
and all of the libraries.
The task manager thread is waiting for the worker threads to exit.
The worker threads are waiting for the last task to be ready to be
cleaned up.
The last task is idle, but with the shutting down flag set and with one
reference. It is a "zone" task.
All of the views have already been cleaned up.
I believe it is this one reference that prevented the task from being
moved out of the idle state, but I doubt that the alleged referrer is
still around.
Without any valid links to follow, I expect it will take code inspection
to find the (apparently rare) path leading to this condition.
