Very sad to hear this .The last modern OS to have true multitasking is also now going the android way.True multitasking was one of the few differentiars for jolla. Many people avoid android and ios only for this particular reason - unreliable app behaviour .People like me care more for real multitasking even more than openness.Why cant it simple give out a warning instead of killing apps..

Have you used the zramcfg in previous versions? I found it still affects Vaarainjärvi if its installed(checked with swapon -s) and after removing it I've had 0 task killing problems even with a lot of applications open. Just a thought.

That is exactly how webOS did it - it warned about 'Too many cards open, close some of them to launch this app' when running low on RAM.

Kernel is just not aggressive enough in swapping.

This won't help you because /proc/sys/vm/overcommit_memory is
set to 1. And kernel docs say that value of /proc/sys/vm/overcommit_ratio is ignored if /proc/sys/vm/overcommit_memory is != 2.
But you can increase swappiness.
"echo 99 > /proc/sys/vm/swappiness"
Also it makes no sense that it is set then by default if it isn't even used. So I suspect it is used. (also I can start a lot more apps with it set to 90 so it must have an effect)

CommitLimit: ...
After testing your solution again it seems it is doing something to help anyway. Both of are solutions together are even more helpfull to situation.
You should put over 100 though.
I did "echo 120 > /proc/sys/vm/overcommit_ratio" .
and
"echo 99 > /proc/sys/vm/swappiness"

With this additional swap i don't have any issues since 24 hours. I will probably add a line to fstab.Code:cd /media/sdcard/*/swapfile dd if=/dev/zero of=swapfile bs=1M count=1024 mkswap swapfile swapon swapfile

Even the calculator is being closed automatically, very handy when one wants to incorporate some figures in an emaill.
