Something else that's happening that might be related to this, or not, is whenever we're running Data Integrity Checks the UPS on the SBS Server sends these email warning messages, sometimes 10 times while the Integrity Check is running: "PowerChute Business Edition has detected the following event: Communication Lost on Agent server". I just noticed today that during the integrity check, the server is barely functiong. The mouse and keyboard are hardly functionable - not responding properly. As soon as the integrity check is done, everything returns to normal function.

If however, we run the Data Integrity Check from the server it is about 10 times faster and doesn't create functionality problems and causes no errors from the UPS.
