This affects linux-aws 4.4.0-1020-aws as well. I ran into this issue on
that kernel.

Seems maybe fixed in 4.4.0-1022-aws

Yea - that 2nd order allocation failure is the exact same issue I was
able to see (same GFP mask also)

I have seemingly solved this issue with linux-aws version 4.4.0-1016-aws
at the very least. The specific issue I was seeing was 2nd order
allocations failing when OOMKiller triggered. At the time I was
thinking the issue was due to XFS and memory fragmentation with lots and
lots of memory mapped
@nicholas-hatch - what file system are your disks formatted as? I was
able to stop the OOM's on my ES hosts by moving from XFS to EXT4. My
belief is that there was a memory fragmentation issue with ES and many
small files on XFS formatted volumes.

We have been seeing this issue recently as well. We are running
4.4.0-66-generic #87-Ubuntu - I can attempt to downgrade to 4.4.0-57 but
its a large cluster with a lot of data so it may take some time.
Attached a kern.log from this most recent oom.

I agree with both Tom and lightraven24, in that adding in packages that
are not asked for becomes overkill when your "container" is effectively
an amazon instance. Having the ability to create a truely "minimal"

Ah - crap - sorry about that. You are right. Thanks!

Title:
Kernel Oops - unable to handle kernel NULL pointer dereference at

I'm still able to recreate this issue with kernel version
3.13.0-52-generic #85-Ubuntu SMP Wed Apr 29 16:44:17 UTC 2015 x86_64
x86_64 x86_64 GNU/Linux
It looks like a different set of audit rules causes the same issue.
To replicate:
Install 3.13.0-52-generic kernel
apt-get install auditd
in /etc
I've tested the build from http://people.canonical.com/~arges/lp1450442/
- and i'm no longer able to replicate this issue. This looks like it
works for me.
