Thanks for explanation, so I shouldn't worry about those. I am asking because I have some stability issues with code and trying to pinpoint it with DETT toolkit. What might not be normal is these startup handshake queues, they should be released after "Ack Startup" right?

Is it normal to have reference leaks on "Parallel Process Library\Create ID notifier.vi" and "Async Execute Core.vi" when shutting down, using startup type 2? When using Startup type 1 only "Parallel Process Library\Create ID notifier.vi" has reference leak. Tested with "vi.lib\drjdpowell\Messenging\Testing\Test Queue Actor Folder\Test error on startup.vi" See picture of trace execution, I''m on LV2018 and latest messenger lib.
