Which services and apps are you running?
If you download the logs what is the date in bios_ver.log ?

Same problem with ReadyNAS 516 when I upgraded to 6.4.2. I get the error every 50 minutes (there seems to be an old thread about 6.1.9 with this issue).
Nothing changed except the version of firmware. UPS is APC Back-UPS RS 1500
I have a feeling that when I reinstalled the UPS it changed serial numbers but can't be sure - just looked different but I had not recorded the old one.

jetheroheller can you send me your logs (see the Sending Logs link in my sig)?
pmk as you have an OS6 NAS as opposed to jetheroheller's NAS which is a legacy one can you open an online support case and let me know the case number?

This is still happening, roughly every 50 minutes, or perhaps hourly on a random minute..
Also, plugging the APC XS1200 into my PC, or another NAS, and it is detected and 'communicates' fine, instantaly, so the wires and the device are probably ok.
