[SOLVED] Kodi using almost all the RAM.

[Exnor]

Hi,
So i got a new "problem" that repeats itself every 3 weeks or so on a non stop Pi being on (btw i never shutdown my Pi 3B+ like i never did for my old Pi 1B for several years, unless its needed of course):

It starts using up RAM and goes up to 78%.... sometimes it reduces the usage back to 60% in hidle but even when i'm not using it the amount of RAM is somewhat too much (?).
Also stats show the average CPU usage is less than 8% even if i'm watching something so i think it's not "processing" anything extra.

When i was writing this:

Terminal

As you can see, at idle is using 68% of the available RAM...

Then i stop/start Kodi and:

Terminal

top - 23:24:04 up 18 days, 21:52, 1 user, load average: 0.56, 0.23, 0.13
Tasks: 144 total, 1 running, 69 sleeping, 0 stopped, 0 zombie

2 root 20 0 0 0 0 S 0.0 0.0 0:01.24 kthreadd

Now its just using about 13%.

I only have a few plugins installed and since the CPU usage is so low (plus they were the same on the Pi 1 and never gave any problems) i don't suspect any of them...

Is this a normal thing now or is this a problem? So far the system as not crashed, but i restart Kodi every 2 to 3 weeks to "reset" memory usage.

Thanks.
