Subject: Apparent leaked task reference leading to hang on shutdown MIME-Version: 1.0 X-Mailer: MIME-tools 5.505 (Entity 5.505) Content-Disposition: inline X-RT-Interface: Web Message-ID: Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: binary X-RT-Original-Encoding: utf-8 X-RT-Encrypt: 0 X-RT-Sign: 0 Content-Length: 688 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.
