I'd like to emphasise that the OOM problem only happens with KDE. I have
several DE installed including Unity, GNOME3, Cinnamon. But none of them
caused a OOM, at least I never noticed. But in KDE, most of the time
when chrome is opened, it triggers OOM. dmesg tells that, sometimes
kwin_x11 invoked the OOM or plasmashell.
Most of the time plasmashell is crashed and the opened tab in chrome is
killed. However, chrome application will be there. I need to start
plasmashell by pressing Alt-F2 bringing the run command dialog and type
plasmashell there.
Last night, Even firefox gave an OOM.
I'm attaching a dmesg log hoping that will be helpful.

Title:
"Out of memory" errors after upgrade to 4.4.0-59
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Xenial:
Fix Released
Bug description:
I recently replaced some Xenial servers, and started experiencing "Out
of memory" problems with the default kernel.
We bake Amazon AMIs based on an official Ubuntu-provided image (ami-
e6b58e85, in ap-southeast-2, from https://cloud-
images.ubuntu.com/locator/ec2/). Previous versions of our AMI
included "4.4.0-57-generic", but the latest version picked up
"4.4.0-59-generic" as part of a "dist-upgrade".
Instances booted using the new AMI have been using more memory, and
experiencing OOM issues - sometimes during boot, and sometimes a while
afterwards. An example from the system log is:

I have a hunch that this may be related to the fix for
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1647400,
introduced in linux (4.4.0-58.79).
