When does Chrome display this frowny face?

I'm seeing this frowny face on Chrome for both Linux and CrOS. On the CrOS system, I noticed some OOM error messages from the kernel, followed by the Chrome process getting killed.

Is this frowny face displayed when Chrome gets killed by the system?

I never saw a screen that only has a frowny face without any test.

However, generally, the frowny face shows up (alongside some text) when a renderer process crashes, or when a renderer process is otherwise unexpectedly killed (either by the user, the system or the browser).

That looks like the icon used when an out-of-process iframe process crashes or is killed. I think the same icon is used for Chrome Apps <webview> and other GuestViews. There's generally no text because it needs to fit in small frames as well.

This happens when there's a crash in either a subframe process or a GuestView (for example, when the renderer displaying a PDF crashes.

It comes from https://chromium.googlesource.com/chromium/src/+/da3587161cce3f1b92c39cab72ee2fe9c482ab0c/content/renderer/child_frame_compositing_helper.cc#231 .

We are seeing this show up on Chromebox for Meetings, running production images in our meeting rooms. I suspected that a Chrome process is OOM'ing and causing the kernel to kill it, leaving behind the sad face. But we are also seeing this in rooms without OOM's.

Now we are not sure what is the cause, nor are we able to reproduce it locally. I can get the frowny face to show up momentarily before our app restarts itself, if I kill one of the renderer processes from the command line.

What would a subframe process or GuestView look like in "ps aux"?

See Google internal bug: b/67870955
