[Bug 1979715] [NEW] out of memory, unantteded killed by kernel. apt-daily systemd fails.

[sascha arthur]

Public bug reported:

had a case where

/usr/bin/python3 /usr/bin/unattended-upgrade reproducable just using
100% cpu and loading stuff into memory, until OOM killer of kernel
killed it.

noticed it because apt-daily systemd failed.

Memory of my machine was 8 GB, nothing else was running.

machine was running 22.04 LTS (yammy, lately installed)

Reinstalled my machine now. If someone hits this, feel free to attach
more information.

Also ubuntu devs should consider to introduce an memory limit for
unattended-upgrade. I mean its unattended, and not nice to flood
"unattended" the memory..
