Problem is still there for me aswell
And I can reproduce it every time now I just don't know what it is, Ive monitored memory during it happening with SSH from my phone using the top command but this isn't memory related, when it freezes it doesn't appear to to run out of memory before kicking me out off SSH due to host going down (because of the crash).
How I can reproduce the problem is by this (even a clean install will do this)
I add my movies location to the library.
I then navigate to movies and my list of approx 100 movies is there.
I keep pressing down on the keyboard going through the list of movies as it fetches posters and background images.
It will then at some point not load poster or fanart for a movie (this is random as to which movie it does this from.
Then I press down again and next movie doesn't load any poster etc, if I press down 2 more times it will then freeze the whole pi3.
So basically if I go scroll down through 4 more movies after the first time it doesn't load poster and fanart that's how I can recreate the crash of the pi
Now the strange part it that it is completely random as to when it decides to do it.
I can do a fresh install add my library and it happen 2-3 times whilst scrolling through my newly added library.
I can do a fresh install and it not do it once whilst adding my library.
And then there are times when I can add one extra video to my library, update library as normal, scroll down to the new film I just added, no poster or fanart appears, this is when I know if I scroll down 4 more films it will freeze (this doesn't happen all the time again it's random).
I've just learned to live with it I'm affraid.
I have to pull the plug every time it does it but I don't know what else to do.
One other thing to mention.
I use a add-on call internet archive game launcher, and this will freeze the pi in the same way.
I choose a game console from the list, scroll through the list of games it will then randomly at some point not load a poster or fanart for a game, if I then scroll down 4 more games the pi will freeze up.
So the exact same problem fetching artwork in a add-on so surely it has to be something to do with fetching artwork that is the problem.
Like I say random when it happens but when it does always freezes up the pi when scrolling down 4 more times.
And just to add that problem has only started happening in version 9 of LibreELEC and does it on all of my pi's which is 2 pi3 and 1 pi2
