Hi,
I received this answer:
i don't know if this is a DNAS issue or a Centova issue as the actual part of the DNAS log output is correct for what it throws. the error in the lines prior to it, i don't know what is responsible for that as i've never seen a DNAS throw such an error and without knowing what Centova is running, i don't have anything obvious to suggest (as i know they've said to post over here, but nothing is obvious to indicate who / what is the cause).
