I have 4.4.0-59 till 4.4.0-71 and 4.8.0-41 till 4.8.0-46 installed on my
system and all are affected by this bug. Firefox, Chrome and Netbeans
regularly get killed without a warning and for no reason (since I have
something like 10GB+ RAM and all 16GB Swap free at the time the process
gets killed). Even KDE has been killed a couple of times while the
system still had over 6GB RAM and 16GB Swap free.
Yesterday, after the umpteenth time Netbeans was killed while I was in
the middle of doing something, I finally decided to do something about
this problem and installed Kernel 4.10.9-041009 from
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.10.9/. Sadly, that
doesn't seem to resolve the problem either and Oom Killer is still
overeager to kill user processes (Firefox and Netbeans have both been
killed multiple times). At least KDE hasn't been killed so far.

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).
