Memory keeps increasing with limited use--diagnosing memory leak issues?

wl246 · April 9, 2025, 4:30pm

I was able to save ps_mem output as well as free -h output after 23h runtime on a clean guest user (with only Konsole and Kate open). ps_mem still shows basically no memory used, but free -h shows 80 Gib used (htop also shows 80Gib used.)

Output pasted below:

at 23hr runtime:

free -h
               total        used        free      shared  buff/cache   available

It seems that this particular bug report and patch was all specific to an issue with task manager (reading the post you linked). I’m not using the task manager at all in my instance, so it seems potentially different. I’m unsure if there’s someone here capable/willing to help me interpret a heaptrack result of plasmashell, since I’d probably get a huge file and struggle to interpret myself. Maybe opening a bug report would be best? I’d also be willing to try gnome or something else to see if the issue is KDE related.

The other confusing thing is that my htop MEM% column and my ps_mem show low memory usage of all my processes including plasmashell, despite the 80+GB of used memory overall. How do I know that plasmashell is the top culprit to check with heaptrack?

Do you have a tmpfs drive that could fill up? In this “broken” state, could you post a df -h and a cat /proc/meminfo?

There are 80 GB in slab, and most of it unreclaimable. That’s very odd. On a “normal” system you would expect a low GB value and most of it reclaimable.

Can you do a sudo cat /proc/slabinfo

wl246 · April 9, 2025, 6:09pm

Sure! Here is the output:

This isnt super readable, but the biggest numbers I’m seeing are for acpi_State and then buffer_head. Unsure why this would be/how to fix

OMG, yes, that Acpi-State number is gigantic.

No clue, haven’t seen that before, but something is wrong in combination with the kernel working with ACPI. Are there any suspicious message in the journalctl -b regarding acpi?

wl246 · April 9, 2025, 6:27pm

Apr 08 12:54:32 wes-wks syncthing[1622]: [AF4ZY] INFO: GUI and API listening on [::]:8080

This is the only acpi related thing I see in journalctl -b. I do remember as of a few weeks ago that when I would try to shut the computer down with the power button, I would see a feed of acpi errors in an interface that looked like cli after the regular plasma stuff was killed, on the way to the computer shutting down. After some googling, I recall I added an acpi related argument in my boot options. Here is my current default entry from ‘bootctl list’

I hope that just removing acpi_enforce_resources=lax will fix the issue. I’m going to try doing that, although I’ll have to reboot. (Lmk if you have any other suggestions!)

Schlaefer · April 9, 2025, 6:33pm

Give it a try. At least we found the missing memory in the slab section - which is usually not reported by free or the other monitor tools - so you can easily check if it increases now (e.g. cat /proc/meminfo | grep Slab)

But no clue what’s causing it.

wl246 · April 9, 2025, 6:36pm

Yes, thanks much for the help accounting for the missing memory! I’ll restart and hopefully report back after some runtime. If removing that acpi related boot option does not fix the issue, I wonder if there’s any way to specifically clear whatever is being stored in the slab section (or if this is advisable).

Schlaefer · April 9, 2025, 6:39pm

Sounds good.

I’m not an expert, I just discovered slab when I finally spend the time figuring out why my memory calculation was always 1-2 GB short.

Afaik it’s memory that is allocated dynamically by the kernel and the user has no way to clear it. There are some vm. params that have control over if it works normally, but then this situation is clearly something that should never happen (bug).

wl246 · April 9, 2025, 6:55pm

Ah that makes sense. Yes, this is clearly a bug! I recall trying to configure VM’s soon after I started using endeavourOS, but I believe I specifically allocated very small amounts of RAM and tried to make sure that nothing would start by default. I abandoned this pretty quickly. Maybe there are some VM related packages I can uninstall (or processes I can kill) that could be related.

Schlaefer · April 9, 2025, 7:02pm

Sorry, I should have been more precise: There are a few knobs in the kernel “vm” as in virtual-memory system that can affect slab behavior (being pedantic here on the point that there are ways to influence some behavior). But these are imho unrelated to this issue, this off the charts and something else.

If you worked with virtual-machines in the past that should not have any influence on this issue.

wl246 · April 10, 2025, 2:16am

That’s helpful!

Well, I removed the acpi related boot option I had and then rebooted. I checked Slab soon after and then checked it again after about 4hr – here are both results

cat /proc/meminfo | grep Slab
Slab:             739196 kB

cat /proc/meminfo | grep Slab
Slab:           20853936 kB

Seems the issue still persists

I realized that I should probably figure out how to disable acpi to whatever possible extent, since there is clearly some kind of incompatibility here. I’m going in order and trying the debugging steps here

Steps printed below:

"The steps below are (pretty much) copied from the DebuggingACPI page and are what I suggest you do to try to isolate the problem before filing a bug report. (I believe the procedures for reporting a bug are also on the DebuggingACPI page)

If acpi=off allows the system to boot, try to isolate the ACPI issue with the following boot parameters. Remove acpi=off and boot with only one of the options below.

If you are lucky, you might find a combination of kernel parameters which allows you to boot and use all the cores of your CPU.

Note: If you need an explanation of to how to do a “one time” change of the kernel boot parameters/options, try this answer to the question “How do I add a kernel boot parameter?”.

Try booting with acpi=ht
This disables all of ACPI except just enough to enable Hyper Threading.

If acpi=off works and acpi=ht fails, then the issue is in the ACPI table parsing code itself, or perhaps the SMP code.

Try booting with pci=noacpi
This disables ACPI for IRQ routing and PCI scanning.
Try booting with acpi=noirq
This disables ACPI for IRQ routing.
Try booting with pnpacpi=off
This disables the ACPI component of the Linux Plug and Play code.
Try booting with noapic
Disables the IO-APIC for IRQ routing or PCI scanning.
Try booting with nolapic
Disables the local APIC."

Thus far I’ve tried acpi=off (results in a failure to boot/frozen screen), as well as acpi=ht (allows me to boot, and initial acpi_state cache in Slab is of size 4590, but it still balloons to a huge size afterwards), and pci=noacpi (again boots to a black screen), acpi=noirq (successful boot, but acpi_state still grows exponentially larger with uptime).

Have you tried to update the firmware? Also, check the power management settings in your BIOS.

wl246 · April 10, 2025, 2:14pm

I updated the BIOS in the middle of diagnosing this (maybe a week ago?). I don’t know much about the power management settings in my mobo–I believe I’ve disabled secure boot and that there may be an additional power management setting I’ve disabled (will take note on next boot)

[Update] – I believe platform power management was disabled in my bios settings. I will try enabling it during my debugging steps to see what difference it makes. As of now, all other debugging steps related to acpi options in my bootloader have been unsuccessful thus far.

chroot · April 10, 2025, 3:50pm

Can you post output of,

$cat /proc/interrupts

wl246 · April 10, 2025, 10:23pm

Thanks for the suggestion! I kind of feel like the computer is screaming at me with this one, lol. The highest entries are:
(9,CPU0) (seems related to acpi and whatever fasteoi is?)
(LOC, : ) (the entire LOC row, corresponding to local timer interrupts)

It seems to me that system acpi states keep changing for some reason. A broken/faulty BIOS firmware could cause this type of problems. But you stated that you have flashed your BIOS.

Let’s see what acpi is doing in the system.


$sudo pacman -S acpid

$sudo systemctl start acpid

$sudo /usr/bin/acpi_listen >> acpi_event.txt

Let it run for a few hours. The acpi_event.txt file should give use some clues.

ok I’ll do this – thanks for all the help!! I see that this last command hangs while it runs–should I just ctrl+c when I’m done with it?
