Tried to look for anything unusual in the emby server log, to no avail (then again I dont really know what to look for.
But... I had a hunch and started yet again Perform Manual Sync, as usual, within a minute it looks like it backing up the internet while it displays "Comparing episodes from: TV-fr..." in the top right progress window.
If I look at the Kodi log while this is happening, its not tv-fr (tv episodes in french) that's being analyzed, its MUSIC.
My music collection is a mere 87Gb for about 16k songs.
Yes, I did include music into Emby, even though I remember overriding a prompt in initial setup that was defaulting not to include music, I wondered why.
There was a 2nd prompt asking if I expect to play this music remotely, I didn't.
