NativePoolQueueSize

(Windows only) The NativePoolQueueSize directive determines the number of threads that can wait in a queue for the thread pool. If all threads in the pool are busy, the next request-handling thread that needs to use a thread in the native pool must wait in a queue.

If a queue is full, the next request-handling thread that tries to get in the queue is rejected and the server returns a busy response to the client. The server is then free to handle another incoming request.
