1964852 - YouTube video yields out of memory (triggering oom-killer) after image freezes

Status: UNCONFIRMED

(Core :: Audio/Video: Playback, defect, P3)

Description

[Vincent Lefevre]

Attachment: System logs

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:138.0) Gecko/20100101 Firefox/138.0

Steps to reproduce:

Play a video on YouTube.

Actual results:

After some time, the image completely froze, but the sound was still working. I ran htop and could see that Firefox was taking more and more memory. When the memory became full, the whole Firefox got killed (not just the culprit tab).

The system logs (attached, starting around the first oom-killer invocation) also show that various processes, including daemons, got killed due to the lack of memory.

Expected results:

The image shouldn't freeze. Moreover, there should be protection concerning the abnormal memory usage.

You have a lot of content processes running. Potentially a lot of tabs open? The oom was detected in pipewire.

(In reply to Jim Mathies [:jimm] from comment #2)

You have a lot of content processes running. Potentially a lot of tabs open?

Yes, but also usually plenty of memory available. Currently, with all these tabs, htop outputs

  Mem[|||||||||||||||||||||16.8G/31.0G] Tasks: 170, 1559 thr, 241 kthr; 1 runn

So, there are 15 GB free. I don't think that playing a video should take as much.

The oom was detected in pipewire.

No, the OOM killer kills random processes (not the one that takes the most memory). Here's what I can see concerning the killed processes for this crash:

If I understand correctly, this ended up by killing Firefox itself (Isolated Web Co).

Note: After this issue, I eventually installed earlyoom, whose goal is to kill the largest process when the available memory becomes low. Now, I can still reproduce crashes with YouTube from time to time, but only the tab crashes.

Here's the crash last night with earlyoom installed:

but I don't understand why there were only 13 GB available for user space. This is a machine with 32 GB memory.

Comment 5

[Vincent Lefevre]

A YouTube tab crashed again, with FF 141.0; it was taking more than 3 GB before being killed by earlyoom.

Note: AutoPlay is blocked and the live video wasn't even being played, but the chat was active.

[Vincent Lefevre]

About the consequence of this bug, i.e. other processes killed before the culprit process associated with the tab is killed, see bug 1787638.
