TaskCanceledExeption related to EPiServer.Find.Api.Command.GetResponse

If you are seeing a high count of the exception type "TaskCanceledException" with "EPiServer.Find.Api.Command.GetResponse" in the stack trace, there could be threadpool starvation (a performance issue) and the search functionality may not be behaving asynchronously.

System.AggregateException: One or more errors occurred. (A task was canceled.) (A task was canceled.)
---> System.Threading.Tasks.TaskCanceledException: A task was canceled.
