I was experiencing a situation with moby dockerd entering a state similar to comment 0 here, running kubernetes and linux kernel 4.15.0-1037-azure. This was an 8 node cluster. Observed with combinations:

kubernetes 1.11.5 + moby runtime 3.0.1 + Ubuntu 16.04.5
kubernetes 1.11.7 + moby runtime 3.0.4 + Ubuntu 16.04.10

The longest window between outages prior was 4 days, with the shortest being less than a day.

I have observed 2 weeks of uptime on 8 nodes without observation of the original symptoms since upgrading the kubernetes node kernel to 4.15.0-1040-azure. I am confident the kernel patch has resolved our problem.
