Bug Report OBS crashes after using up all 10 gb of ram and causes PC to crash with it

[prostreamer]

My PC has been crashing regularily on archlinux shortly after obs using up all the ram. as you can see in the picture attached obs is using 10.5 gb of ram. all other apps are using ram in mb only(less than 1gb ram).
it is worth noting that I'm using the browser plugin qtwebkit provided by bazukas (third party) to display chat.
as you can see in the picture the obs was fully maximized (not minimized as some solutions suggest in the forum)when it happened.
Interestingly enough the last time it happened i didn't even start streaming yet. so the problem is happening with obs open with or without streaming on.

maybe limiting obs to 8gb ram may prevent pc from crashing at least but will still cause obs to crash.
I have 12 gb ram and no swap partition.

any ideas?

Known issue, but no concrete solution yet.

 

[prostreamer]

Thanks for the quick reply. indeed this does address the issue. However due to my limited knowledge I have no idea how to "Add xcb message poll to empty out the queue"

I have previously installed obs on archlinux using:
sudo pacman -S obs-studio

is there a file i can edit to add the necessary change, or do i need to uninstall obs then reinstall directly from github?

 

[Fenrir]

That is just explaining what the issue is. If you want it fixed now, you'll need to compile OBS yourself from master on the github repo. Check the install directions relevant to your distro.

 

[prostreamer]

I uninstalled "obs-studio" using the "add/remove software" app built-in arch/antergos.
reinstalled obs using the following commands:

$ git clone https://aur.archlinux.org/obs-studio-git.git
$ cd obs-studio-git
$ makepkg -sri

after installation complete i checked "add/remove software" to see what obs version was installed and i found :
obs-studio-git 0.16.6.r29.g1865285-1

although the names are different "obs-studio-git" and "obs-studio" all settings and were saved from previous installation including the browser plugin i have previously installed.

I will leave the stream running for a few days and see if the ram problem persists.

okay so i just built from scratch to test, i was looking around and found several other bugs same exact thing. After building i found the issue was solved somewhere in the commit history.

after building i monitored the memory usage and it was consuming a constant 52mb on idle after opening settings, on last version it started at 82 and went up

basically you have to either build yourself to get rid of the bug or wait for the next update

Had there been a solution to this yet? It happens on windows as well.

 

[Fenrir]

No, it doesn't. This bug is specific to Linux only, and does not affect windows in any way. Your issue is not related. Please create a new thread in the appropriate section and provide the full details of what is going on, with a log file from OBS.
