[SFOS][1.1.0.27][OOM] The death of multitasking?
 
My thoughts are not yours and I and I do not like anti-features.

It is me, myself and I not you, yourself and you and if you decide to kill me than please kill me softly.

We are the world, we are the sailing children. Please swapon.

Been very busy, just using the device as phone, not too heavy as I don't have interesting enough soft on Jolla to demand heavy.multitasking in my ussage pattern but I was already wondering: where did those open windows go.

I did not close them!


If I d want to have an over zealous house maid I d move to Android.

At this point I'd expect a slider for OOM operation behaviour.

Sure stuff is fluent but so is my N900 with more work at hands.

I wonder if Maemo core be the best for multitasking? Hmm.. N900 and N9 has very good multitasking, Jolla.. Ok, but not that good. Other than that, Jolla is the best now :). I still have them all ;)

I think the problem with this killer is that it starts killing even if swap is still free. So just a configuration that needs to be changed. Still searching for that config though as I am not sure if its a jolla made killer or the global inbuilt linux kernel oom killer.

The problem?
OOM has been optimized in update 10.. it's surprising Jolla considers this the fruit of months of hard labour.

It would be great if the config could be tweaked but if it is really so hard to balance it I 'd expect Jolla to share the previous config and the new 'Android one'

Did not test the opt in update, but I suppose it worked still like the old Sailfish release for what concerns OOM?

Yes, but in case memory was full, there could be some pretty heavy lags. I'm not sure what I'd rather read complaints about on TJC: lag when doing anything, or closing applications automatically. Hopefully this behaviour can be edited somewhere to allow for a bit more time before applications close themselves.

Code:

cd /media/sdcard/*/swapfile
dd if=/dev/zero of=swapfile bs=1M count=1024
mkswap swapfile
swapon swapfile

With this additional swap i don't have any issues since 24 hours. I will probably add a line to fstab.

Digged around a little bit and found the config to tweak the OOMKiller behavior.
At least for my workflow it now allows opening up more apps than before before OOMKiller kicks in and kills some.

Made a thread on together jolla open for discussion: https://together.jolla.com/question/...t_ratio-value/

Thanks for this!
