I've been running sbws for about 5 days without checking on it.

The first time the following exception appeared in my logs, I went from seeing a variety of thread names in the logs to only seeing a couple. This indicates to me this is (a/the) exception that has been causing sbws to fallback to just one measurement thread. (Later instances of this exception don't change anything)
