Probably it's not a bug in fact but a feature more likely. But the question is if it shouldn't be changed a bit.
In several most fresh LE 9.80 Nightly test builds on my RPi 4B / 2GB I have experienced several unexpected crashes due to Out of memory event when oom-kill intervened.
That's due to my Timeshift settings in Tvhedadend to use RAM only with Maximum RAM size set to 1024 MB. This limit I set in past experimentally by observing the Free memory value in Kodi / System info / Summary. So now after crashes it seemed that LE is using more RAM and I'l had to decrease the Maximum RAM size to avoid Out of memory.
But I have found that the Free memory value is calculated and it is somewhat greater than free / avail Mem values reported by the top app.
It looks that Free memory formula is Mem total - Mem used but this value is greater than Mem free / avail Mem reported by top so there's an overhead somewhere.
This may be misleading as I would expect the Free memory in Kodi should display the lowest - real - value.
I wonder why the Free memory is calculated by formula and why it does not show the free or avail Mem value instead? I suppose there's a reason but shouldn't be that changed?
