Metadata Improver error message

Hi Noris,
The Core from which i grabbed the logs is a native QNAP image,

The QNAP is a TS-470 Pro, with 16Gb RAM and upgraded CPU (Intel Core i5 3470T) and the Roon DB on a dedicated 128Gb SSD and three 6Tb WD Red in a RAiD5 cfg.
It is connected to an ASUS RT N-66U which is set as an Media Extender over 2.4Ghz WLAN. The media extender connects to my main router which provides Internet access, an Asus RT-AX58U.
The AX58 is connected to a HP ProCurve unmanaged switch which gives wired connectivity to a couple of endpoints and other network items in the household. Oh, all wireless devices connect to the AX58 on a separate 5Ghz WLAN.

But, i have this issue on my MOCK right now also, which is displaying it right now. And that one is wired to the ProCurve and on to one of the AX58’s LAN ports. (The WAN port on the AX58 is directly wired to the FMC in my apartment)
