Your snippets from logs are symptoms. They just show the exception thrown when something tries to create a thread and there is no more available. They don’t show what is using them in the first place.
Is everything up to date? Disable all your bindings and then enable them one by one. When the thread count spikes you might have found the root cause/binding.
Yes exactly. I was after the tree view and thread names. When I had almost 2k “dead” threads I could spot it from the listing that there’s just too many.
