On the longer video it looks as though the memory use is climbing constantly. Any ideas how I can help debug this a little further or know what the issue might be?
Sorry to see you are experiencing a problem.
Has this started recently?
An out of memory issue would cause Kodi to restart.
It doesn’t look from your video that the device is restarting; but rather Kodi is; so logs should be valid.
I pulled the power cable earlier so definitely had a full reboot, which I think would cause the logs to go. I’ll give it a go again later to see if I can get you some logs to look at.
Just happened when I tried to move to the next chapter in the movie.
*edit
Looking at the logs it looks as though there is an issue with PlexKodiConnect which is throwing up a load of errors! I’m guessing that is my issue right there.
