One of my main issues with OE was ram management, after using a few addons (youtube etc), browing the library and playing a few videos, ram would quickly fill up to about 65%, once playback was stopped it would not release any ram until you rebooted the box. This would result in slow performance and then freezing once ram got to about 85% used which required a hard reboot.
This is 10x better on LE but ram slowly continues to increase on LE as it did with OE, and it is not being released. On my raspberry pi2 running osmc ram is always below 30% when idle regardless of what addon was used or what video was played. This seems like an OE/LE issue vs a box or build issue to me since on osmc i can go weeks or months without rebooting or freezing with pretty much the same configuration.
Let me know which logs you need and i can get them for you, i keep the rpi2 on 24/7 and would like to do the same with these s905 boxes and not have to worry about rebooting or freezing.
My mxq has 1gb ram 743MB usable, 590MB (21%) free on boot.
Regarding the power off issue from the remote, its actually not going into suspend/standbuy. Its just turing off the hdmi output to the tv, if you wait about 20 seconds the hdmi signal is restored.
Edit: Attached is the log of a fresh install on an SD card with a random bunch of kodi video addons, the box boots up with about 20% ram used and after playing, skipping, browsing different addons you can see ram slowly filling up. I took these logs at about 52% ram used, it will not freeze until it gets to about 85% which will happen in a few days if the box is left on 24/7.
I have similar experience on Mini MX 1GB RAM, not only kszaq's LE build but also alex's OE build. Memory usage figures are about the same. I tested with 2160p x265 10bit videos (on my 1080p TV), playback won't even start if memory usage is over 50%. If I stopped playback at the middle and switch to another, playback couldn't even started as memory usage was almost 70%.
Is there any background process running that keep the memory from releasing? Also if I populate my video library, I would never see memory usage below 35%.
