steamwebhelper eating all RAM _AND_ swap until it gets OOM'd

blisskidd commented 4 years ago

Your system information

Steam client version (build number or date): Built Jul 8 2020 @ 23:11:02
Distribution (e.g. Ubuntu): Gentoo
Opted into Steam client beta?: [Yes/No] Yes
Have you checked for system updates?: [Yes/No] It's fresh.

Please describe your issue in as much detail as possible:

What the title says. This has been noted before under issue 6502, which is closed. This started happening shortly Screenshot_20200715_101644_steamwebhelper after my last client update. I have steamwebhelper growing to somewhere north of TWENTY GIGABYTES of memory usage.

It's also WORSE than Issue #6502 (https://github.com/ValveSoftware/steam-for-linux/issues/6502) was, because even if I mercilessly slay these processes before they quite get that big (it does take several seconds) enough to get into the settings menu and disable the interface acceleration options... it doesn't stop doing it. I literally have ALL of that turned off.

Steps for reproducing this issue:

Launch client.
Wait a few seconds - watch your processes with ksysguard or top or whatever your favorite is.
Observe all system memory being fully exhausted by steamwebhelper, and then all available swap (granted, I only have 16GB RAM and somewhere around 5.5GB swap allocated...)

Is there any useful log info I could possibly generate to help point in the right direction? Part of me wants to try wiping / moving my ~/.steam - but I also live in a very rural part of North Carolina and it would take me literally all day to download games again (though I suppose I could backup/restore from my laptop...) but I guess what I'm asking is... ...is there a log I can look at somewhere?

blisskidd commented 4 years ago

Update: Tried a round of mv ~/.steam ~/dot-steam-is-this-the-problem (and logging in fresh). No dice, steamwebhelper still runs away with all my RAM within seconds of trying to show me the store page (which doesn't display, either... clue maybe?)

garyttirn commented 4 years ago

I've been getting the same issue on Windows 10 too, on two separate computers, a laptop (intel i7) and desktop (AMD 2950X), both with Nvidia GPU (M840 in laptop, RTX2060 in the desktop), generally with latest Nvidia drivers.

I think I first saw the issue around spring time (Feb/March), but I haven't had much time to play games so I didn't bother to investigate further after I found a workaround. Several Steams updates after that and issue is still there, tested latest with Jul 31 build.

The workaround is disabling the builtin browser component from Steam with command line options -no-browser steam://open/minigameslist

I did try all the other workarounds mention in Issue #6502, but none of those made any difference.

garyttirn commented 3 years ago

Seems Steam client build on 10th December 2020 no longer has this issue on Windows 10, I have not checked Linux yet.

alamar commented 2 years ago

Still see this issue! Does not happen outright but eventually it will start eating all RAM.

CtrlAltDeplete commented 2 years ago

The last time I noticed my memory usage skyrocket was upon launching dota 2. Memory went from a couple 100MiB (still high) to 4GiB. Any logs I can capture or memory profiles, just let me know.

RenaKunisaki commented 2 years ago

Just started happening to me today. Somehow multiple steamwebhelper processes all decided they needed all 32GB of RAM, and even killing them doesn't help because they immediately start back up and go right back to 32GB instantly. I have to use -no-browser now to use Steam at all.

CtrlAltDeplete commented 2 years ago

@kisak-valve As of July 1st, 2022, the steam webhelper got up to 50GB in a day. Just updating/pinging to keep this fresh.

Seralyne commented 2 years ago

@kisak-valve As of October 31st, this is still an issue.

Additional information: Distribution (e.g. Ubuntu): Arch Opted into Steam client beta?: [Yes/No] No Have you checked for system updates?: [Yes/No] It's fresh.

There is a temporary workaround that I found around the internet, that I can confirm has worked for me:

Disabling GPU Hardware Acceleration for the web components in the Steam settings, as well as enabling Low Power Mode seems to have essentially entirely eliminated the memory leak.

I seem to be hit by the same issue. However, the problem only started about a month ago for me, which should coincide with the release of the new Steam GUI.

Description: Randomly, my system will lock up entirely, forcing me to do a hard shutdown. I have plasmoids for various system data on my desktop, which allowed me to deduce, that my RAM and SWAP was being used up entirely by something. Each crash is being reported by my system as follows: Not-reportable: The backtrace does not contain enough meaningful function frames to be reported. It is annoying but it does not necessarily indicate a problem with your computer. ABRT will not allow you to create a report in a bug tracking system but you can contact kernel maintainers via e-mail. Reason: traps: steamwebhelper[3412] trap invalid opcode ip:7f977cac013b sp:7fff085b7780 error:0 in libcef.so[7f97788ef000+7770000]

Workaround: None that I know of. Support for -no-browser has ended: Ending support for -no-browser Trying out disabling GPU Hardware Acceleration for the web components in the Steam settings, as well as enabling Low Power Mode

pokemonpasta commented 1 year ago

Still an issue for me. This has been a problem for a while but usually it was only 100-300MB, whereas recently it has increased to upwards of 600-800, which is actively hindering my gameplay.

Additional information: Distribution (e.g. Ubuntu): Kubuntu 20.04 Opted into Steam client beta?: [Yes/No] No Have you checked for system updates?: [Yes/No] Yes, no updates

I already have hardware acceleration disabled, I'll see if Low Perfomance Mode helps but I don't have high hopes

bryanspears commented 1 year ago

This occurs very often since the recent major update to the steam client and it's a sudden gobble from 0 to dead in less than a minute. Not sure of the trigger, but it seems like state changes such as leaving a game or getting a steam updte make it crap out quickly.

Using "steam native" (not the built-in runtime) caused it immediately just now as a test. Start to OOM killed in about 10 seconds.

laurirasanen commented 1 year ago

Lately I've noticed that steamwebhelper builds up to >10GB of memory and ~1-2% cpu usage in the background (steam running but no windows open). However, actually opening the client will immediately drop the usage back down to ~0.4GB and 0% cpu. This seems to happen at least once a day.

Leaky core dump?

I took a core dump with gcore -a $pid while the memory consumption was ~11GB and noticed a lot of repeating sections in it with objdump. The core dump file is ~17GB.

The biggest one I found is this pattern:

 657b7c48000 60c3e88f 57060000 c083e28f 57060000  `...W.......W...

There are slight differences in content but the surrounding bytes seem very similar.

Counting the instances with objdump -s core | grep -o '$pattern' | wc -l returns:

00282b1e 01000000 00000000 00000000 -> 44909242
e081e48f 57060000 00000000 00000000 -> 44910561

Assuming the pattern is unique and 224 bytes each that's ~9.4GB, which could explain the majority of memory usage.

Some smaller repeating sections:

This 192 byte section shows up quite a bit:

 370372be820 7b14ae47 e17ad43f 00d6e08f 57060000  {..G.z.?....W...

 370372be870 00000000 00000000 00000000 00000000  ................

7b14ae47 e17ad43f returns 6415600 instances, assuming unique 192 byte sections, that's ~1.1GB.

I would guess this is a container type for something. Some of them have data, such as this one which has numbers stored as strings:

 3704250bdc0 7b14ae47 e17ad43f 00000000 00000000  {..G.z.?........

Searching for 01000000 36000000 00000000 00000000 returns 6415600 instances. Assuming unique and 128 bytes, that's another ~0.8GB. Curiously the count here is exactly same as for the previous pattern.

Fresh core dump

steamwebhelper uses around 0.4GB of memory after fresh launch and the core dump file is ~4GB.

Searching for the same patterns after a relaunch yields counts:

00282b1e 01000000 00000000 00000000 -> 913 (down from 44909242)
e081e48f 57060000 00000000 00000000 -> 0 (down from 44910561)
7b14ae47 e17ad43f -> 77 (down from 6415600)
01000000 36000000 00000000 00000000 -> 82 (down from 6415600)

Going through the matches is a lot easier with so few results.

00282b1e 01000000 00000000 00000000 seems like a list of *something binary*:

HUEMOB commented 8 months ago

I’m also having this issue. I’m on Debian 12 stable with nvidia. When I run a game it works for 20-30 mins and then my whole system freezes due to running out of memory. I have 16 gb which should be plenty for the games I’m running but the steamwebhelper just duplicates like 10-15 times and eats up my ram until it dies. I don’t use steam as a browser I have no tabs open in steam or anything like that. I tried turning off gpu acceleration and turning on low performance mode and this only helped the games run for a little longer before freezing but it still happens every time. It’s really disappointing how they don’t seem to care about fixing this issue.

I am having this issue on arch after updating. 5 minutes after launching, it eats 16GiB of RAM.

sleep-walker commented 3 months ago

I experience it on openSUSE Tumbleweed.

[29362.388821] Out of memory: Killed process 144041 (steamwebhelper) total-vm:51187620kB, anon-rss:580688kB, file-rss:268kB, shmem-rss:228356kB, UID:1000 pgtables:3004kB oom_score_adj:300

it seems to me to be linked with notification

Neubulae commented 2 months ago

How would I diagnose this issue? I think I'm experiencing similar problem but I am not quite sure why and what is happening

Dude this might actually be a hint of sorts. What media could it be trying to seek to 0.0 of (0m.0s) - I think this looks like browser guts, in which case -something- is making it think it's being told to go to the beginning of some media or other... maybe it's doing so multiple times, resulting in the embedded browser loading said media object (not sure why it's doing it repeatedly like that though - or rather, what's generating what it thinks is input to do so - scripted probably - but while preloading one media object to play back shouldn't murder a typical machine's memory pool - now... multiply that memory usage by thirteen times and NOW you have a problem!).

Can I get an opinion out of @kisak-valve ? ...do you think I'm barking up the right proverbial tree, here?

I'm still game to try to help you guys figure out what the cause is... even though I haven't seen it do this in quite some time (disclaimer: Gentoo with a moderate mix of ~amd64 packages... I can bet you my userspace bits are newer than yours, and MOST of the time I'll win that bet...).

Those strings are from chromium logging and only amount to a couple MB. Could be a red herring unless it also holds on to some larger media related data when spamming those logs.

I no longer experience the leaking issue but I still have the coredumps from november last year if those are of any use. It's 7 dumps total from 2 days, ranging from 0.4GB to 11GB memory usage.

Still an issue on 6.10.10-arch1-1.
