Title:
4.4.0-83-generic + Docker + EC2 t2.small frequently crashes at
cgroup_rmdir GPF
Status in linux package in Ubuntu:
Confirmed
Bug description:
We run xenial-based Docker container hosts on EC2 with Amazon ECS.
Recently we refreshed our base image, we started to see frequent
panic.
Hosts run Amazon ECS Agent, and the agent automatically creates or
destroys Docker container based on requests onto ECS cluster.
I think this crash is caused by Docker-related operations, because
crashing at cgroups.
Also, we're running several different cluster with another EC2
instance types, using same image. This problem is only reproducing at
t2.small instances. (We also run c4.large and m4.* clusters)
Our previous image ran 4.4.0-79-generic, and we see no problem with
79.
