It's the cache, I pin-pointed the main problem correctly without ADB access, any closer details and just google.

Looking further into the issue disk space is a huge problem with Kodi discussed plenty of times. In fact even the Wiki dedicates 2 pages to it:

I realize from your perspective this may seem still a very convincing example in the sense of it works.

A non-programmatic solution might have been possible though:

> It's likely your thumbnail cache. That's typically the biggest piece stored locally (you also have the database). You can clear the cache (short term fix) or move it to another drive (long term fix).

> Also recommend not downloading actor thumbnails. Lot of extra images.
