Hmm. I just remembered that I have a second infrequently-accessed database which is also configured.
So I'd really have 3 runtimes * 2 connection pools, so that explains 6 of the 8. Not sure where the other two are from unless I have a 4th runtime that I've overlooked. On Cayenne 4, yes, that's one of my goals this summer -- upgrade to Cayenne 4. Probably won't happen until July, though. I'm going to add something that will dump all threads when this exception is hit.
