Problem..

The log shows a huge number of requests from the device with IP address 192.168.0.20 to retrieve embedded album art from the file:
Lossless music/Steely Dan/Then and Now - The Best of/02. Steely Dan - Rikki Don't Lose That Number (-74) (Then & Now - The Best Of Steely Dan - Remastered).flac

MinimServer is sending the album art data but the 192.168.0.20 device is rejecting it and immediately sending another request for the same data.

This cycle repeats hundreds of times until MinimServer hangs, presumably because some internal resource has been exhausted.

This is effectively a denial of service attack on MinimServer by the device with IP address 192.168.0.20. What is this device?
