Description Chris Murphy 2022-06-10 14:53:44 UTC
Description of problem:

There seems to be some kind of extreme memory leak with this version; a zoom session, within minutes, consumes all memory and swap.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Start a zoom session

Actual results:

Within minutes, all available memory and swap are consumed, and oomd kills the scope assigned to the zoom session. All of Firefox ends up killed too, not sure why.

Expected results:

Shouldn't need such extreme resources.

Additional info:

If I mask oomd, the resource consumption results in the entire shell freezing, including the mouse arrow, and nothing immediately before and including this makes it to the journal. So the logs show nothing, they just end. After a minute of this state, I just forced power off.

The only hint I see in this entire log is from oomd at the time of the kill:

Jun 10 09:45:50 fovo.local systemd-oomd[662]: Killed /user.slice/user-1000.slice/user/app.slice/app-gnome-firefox-4369.scope/4369 due to memory used (16076365824) / total (16403767296) and swap used (7871721472) / total (8589930496) being more than 90.00%

It looks like we're in the same boat, see BZ#2095718.
