All right. About every five minutes or so I get three-to-five instances of this exception showing up in the wrapper log. I’m pretty sure this is having to do with the connection pool somehow, but I can’t seem to find where the offenses are taking place.

Attached is the wrapper log. Any pointers?

Hi Jordan,

Do you have the “Test on Borrow” setting in your datasource configuration set to True?
