Package: kded5
Version: 5.28.0-1
Followup-For: Bug #879901
Control: severity -1 grave
Raising severity because 6520.81MB is enough to make the OOM killer
kill a browser on a laptop with less than 8GB of RAM, when the user is
running without swap (possibly also with zswap) because he/she is
using an SSD, or to make the system swap so hard that it becomes
unusable. Please see #879898 for Simon McVittie's analysis about how
this issue also causes the user's session's dbus-daemon memory to also
balloon.
Please let me know what I can do to help debug this further, because
I'd like to help solve this asap. This time I triggered the issue on
my desktop. Please note that while my desktop is running a custom
kernel, my laptop is running linux-4.9 shipped in Debian Stretch. I'm
sticking with 4.4 on my Desktop, because linux-4.9 has a couple of
btrfs regressions that haven't yet been patched...I don't take risks
with my primary system.
