Yes, that is helpful. It further confirms my suspicion that thread pool threads are being leaked. On top of the fact that the error message explicitly states there aren’t enough thread pool threads, the setting for `MaxThreadPoolWorkerThreads` defaults to `2048`, which is suspiciously close to that count of total threads used.
