Hi Weston, Yeah, it is quite weird. It was my understanding that the new-connection-sql would help detect the case when a new connection was fouled up for whatever reason. Would it be possibly to turn on some debug/trace level logging to pinpoint exactly what is going on, or at least to try and get some more information?
