 Is there anything to be found here?

Not particularly, as it doesn't show any out-of-memory event taking place. Also, memory that is leaking doesn't really leave much trace in the logs (unless there is an OOM event) which is why it's so hard to pin down.

You could try running bcmstat.sh -ZAD d30 and see if you can correlate the memory allocations to your activity.

Also test with a clean .kodi - no extra addons. If the problem only occurs once you install Emby, then contact the Emby developers.
