Copious logs from containerd

[flah00]

Issue

Every ten seconds containerd logs

time="TS" level=info msg="containerd: ID (pid PID) has become an orphan, killing it"
time="TS" level=warning msg="containerd: unable to save ID starttime: open /proc/PID/stat: no such file or directory"

I haven't been able to track down the source, but it happens in the two environments I run.

Software

kube-aws: 0.9.7
docker: 1.12.6
containerd: 0.2.4
CoreOS: 1409
kubernetes: 1.6.3

This looks like moby/moby#28336. This was fixed in #351, which was released as part of docker 1.13.

You'll have to upgrade docker to resolve this.

Let me know if you have further questions!
