All of my t2.micro & nano instances are affected by this in AWS EC2 after upgrading to Ubuntu16.
doing "echo 1 > /proc/sys/vm/drop_caches" (also tried echo 3) works for a short period of time, but it comes back within a few minutes.
I moved a couple instances over to f1.micro on GCP / GCE (1 vCPU, 0.6 GB memory) and the problem seems to have gone away. I can't do this with all of my instances yet though so a fix in AWS would be nice.
