Bug Description
This may be a very complex scenario with several components involved. But it ends up in v4l2-relayd having allocated 6GB RSS memory, and suspect this memory increase to be the problem, or is it just a side effect?
I have seen this error a few times now, and it involves bluetooth, Microsoft Teams and possibly also Chrome.
It occurs when I start a Teams meeting, but my bluetooth headset is not connected (possibly a bluetooth bug also). I then do something to activate bluetooth, and then my computer freezes, for half a minute (feels very long). When it becomes alive again, then I can see the OOM in the attached syslog snippet - and Chrome is also killed!
