The values in the XA2 series phones are already minimal, thereās no benefit taking them any lower than that.

On the contrary, I didnāt see very positive impact by changing to Sonyās default values with 10 II. Weird freezes with apps and OS crashing etc. Switched back and I see the reason for 6x.

Good to know, interesting!
Just a quick update!
I have been using the minfree values of 65536,73728,90112,131072,196608 and so far I have been very happy with these! While I may not get the maximum amount of opened applications at the same, I think 12 is plenty good! Iāve also had zero OOM kills since.
I stand my opinion that the X10III ships with too conservative memory limits and they can be safely lowered to some extent without risking OOM at application startup, and providing a much better user experience.
Edit: I simply havenāt had more than 12 apps opened at the same time.

Didsomeone find something that helped with the 10II ? I tried half of jollas defaults and got weird crashes

I tested the halving briefly, and had similar results, unfortunately.
It looks like the limits are quite well tuned for X10II. If that is indeed the case, I see no reason to double the values for X10III only because it has double the RAM.
We are slowly narrowing the acceptable window here, which is good

Itās been two weeks since Iāve been using halved values on the 10 III, without any problems and with not a single occurrence of closing any app due to OOM, with the single exception of the web browser, which happened once. So Iām more than satisfied.

My experience showed better results when halving the freemem values on my X10II. With the default settings, the Android App Support system gets killed most of the time after I watch a video in Fennec (Androids Firefox Browser), as soon as I stop using my device. Next time I turn on my screen, all Android apps are greyed out and opening one of them starts the Android App support first.
Since I started adjusting the freemem values, this rarely happened.
As Iām only using a few apps on my phone, this may not be the average user use case.

joining the boat here just tweaked minfree on my 10 II with 58580,70100,81620,93140,128245, I have 4 Android apps open + stock browser + Fernschreiber, and the system is still smooth, and no crash so far

So I just changed my default values after I really got sick with apps closing down randomly. Following @cartronās tweak I changed from
[root@Xperia10II-DualSIM defaultuser]# cat /sys/modul
e/lowmemorykiller/parameters/minfree
117160,140200,163240,186280,256490
to
[defaultuser@Xperia10II-DualSIM ~]$ cat /sys/mod
ule/lowmemorykiller/parameters/minfree
58580,70100,81620,93140,128245
I will report back in the next couple of days whether I experience an improvement or not.
What I learned so far:
- I have to set the limits after every reboot
- Fennec can be killed like before

I have also modified the config on my 10 II.
Here is my experience:
- Apps no longer close on their own.
- Got 3 cashs in 2 days (0 in the last 6 months)
I am back to the default configuration.

I was hit by random OOM kills, too that made using the device (10 Mark 2) nearly impossible.
There where a few things I recognized:
-
SailfishOS browser pinch-to-zoom eats memory, e.g. open some github project source code file and zoom in. Now scroll a little bit inside that zoomed file and bang there you go (LMKD is killing a bunch of running applications in a blink)
-
I had a memory leak caused by faulty / broken Sailfish MTA that consumed a lot of memory but alas itās a system process so other running non-system applications got killed first
My solution to the latter issue was to re-create my mail account which resolved the MTA system process memory leak that caused LMKD to hunt down my other non-system applications.
Now thatās what I call āinterestingāā¦ How did you figure it out that it was the MTA process that had the memory leak? Asking for a friend

To be honest I had a bad feeling when syncing my mailbox (IMAP4) suddenly took very long and ended eventually with sync failures. After that I recognized that running multiple applications (Android: ntfy.sh, Schildichat; SFOS: Mail (backround), browser, Quickdit, forum viewer, Podqast) where killed overnight.
I didnāt dig any deeper nor analysed logs (which would be more objective). However after I fixed my broken mail account no overnight or common use crashes of running the same set of applications occured to me (knocking on wood).
What I wanted to say is that system processes are allowed higher memory demand before they are terminated so in the end faulty system processes can trigger the LMKD killing of unprivileged processes and you wonder why the heck are my applications crashing all the time.
I updated to 4.4.0.72 and my changes to the /vendor/etc files was reverted. Just realized when I got pulseaudio killed today (or yesterday).

yes, this doesnāt survive a reboot.
Iām looking at options, it looks like using udevadm could be an option, iāll try to find some time over the week-end to look at that, and will report back.
typo in your formula
it is *4 / 1024
You can edit this file, it will work till the next OS update. The numbers that direc posted last were the best I think, or values used by 10 II, both quite similar.
omg was to stupid to click on insert in vi
LOL
thanks
