could you play a little more with 'top' using 'f' and 's' to sort by VIRT or RES to see what is growing exactly, the default sort (Cpu) not being of much use here. If signal-desktop is not the culprit in this case, it may be whatsweb for example.

If you look at the last top I posted I sorted with %MEM which is equivalent than sorted by RES. And there is seemingly no process that eats too much RAM. I've never seen in a top any processes consuming outrageous amount of RAM.

I've also done a df -h , to see if a ramfs could use too much space but I've seen nothing.

As you tell me that "the swap handling is not the 'classical' sort, it's the more advanced type of 'compressed Ram'", I wonder if the swap itself could be buggy?

That's very strange. I had kept a copy of top when the dialer had crashed my phone and it was clear that there was a culprit:

Also do you see kswapd taking a lot of Cpu like in my top ?

It's probably the same software and setup for all ports since it's not linked to Android.

No but I did not pay attention either, I will next time.

It's probably the same software and setup for all ports since it's not linked to Android.

But I would be very curious to know if the action that I mentioned previously is reproductible for other VP22 users and non-VP22 users: importing a picture with contentHub directly from camera app to Whatsweb (probably works with another app than whatsweb), does reduce progressively the amount of available swap, when done several times, without any clear reason.

Because on my side it does it reproductibly, it's probably not the only action that triggers that, and it kind of explain why I end up without swap.

I tried to repro on my FP5 without success, but of course there are many differences: other phone, more Ram (I have 8 Gb hence a swap of 4Gb) , I don't use Whatsapp or Signal so all the apps available to share in contentHub are files and messages. After a dozen of shared photos, zero swap, available memory in top goes down by one or two hundred of megabytes, then back up.

Have you tried to lower the swappiness of the system? Maybe this could help to slow down the use of the swap-partition. On my phones (and Laptops) i set the swappiness to 10:

sudo sysctl vm.swappiness=10

If that works for you, you can make this permanent via a config-file

Thank's a lot but I not sure to see how you can do it with files apps (or maybe there are import features that I don't know about, but I really don't see where).

Just to make sure I was clear with messages it would be:

1-Open messages app
2-Go to a conversation and click the attachment icon, then image
3-In contentHUb select camera
4-Take your picture and validate

I will to some more tests tonight including swapiness.

It does not seem to have clear impact on swap loss when importing from camera. I will see if the crash still happens in normal use, with this option in the coming days.

@pparent

thanks for the explanation, it's indeed faster than the more convoluted process I was following. So I did about 6 messages each having 5 photos, lomiri-messaging memory footprint increased steadily by about 100 K for each message (that I never actually sent, it was a dummy number). When I closed lomiri-messaging all this memory was reclaimed by the system, and if I open it again I don't get back the high memory use even if I open the same contact.

So there may be a leak but it hardly seems a blocker on my phone - that is, my current use of the phone is that as soon as I have finished using an app, I close it, and each evening I shutdown the phone for the night. You may use your device very differently of course.

I've upgraded my Volla (yggdrasil) yesterday from 20.04 OTA-11 to 24.04-1.1 stable. Since then I already had two times where the phone freezes/crashes. When I press the power button to wake up the phone it seems that only the backlight is on but there is no picture. If pressing power button again, the backlight is off again. I can repeat this procedure several times without luck. Several minutes later the phone again wakes up like expected while pressing the power button.
After having a working phone again I checked the RAM&SWAP. Both of them were not totally used and had some reserve. Then today I tried to flood RAM&SWAP by starting many different apps and after a while my SWAP was filled 100% while the RAM does still have some free space. The phone is still usable and is not freezing/crashing...

Yes I use to keep whatsweb always open to get notifications, and I rarely reboot the phone if it does not crash, except if I somehow run out of battery which happens rarely given the very good battery life of the phone

Those days I've not experimented any crash. I'm not sure why. The difference might be that during the Christmas celebration, I've shared and received and taken many pictures with messaging apps. But it might be something else. Because the leak that we have noticed seems to require too many imports to explain completely the problem.

Well thank you for reporting, maybe you can add your experience to the bug report, so that it is clear the bug is not specific to my phone:

@pparent Sure, I can complement your bug report. But do you have the same experience?

Press power button
Backlight powers up
No image is coming up

Yes I've seen it a few times as you describe, but most of the times I had a freeze with still image while using the phone and using the interface. In that later case the phone stays still in the last image, and pressing the power button does not have any effect. So I guess what you describe can be the same bug except that it happens while the phone is suspended, so when you press the power button it remains frozen on a black screen.
