I'm still able to duplicate this bug using: linux-image-3.13.0-78-generic (from trusty-backports) linux-image-3.19.0-50-generic (from linux-image-generic-lts-vivid)
The LXC images failed to start under linux-image-4.2.0-28-generic, with a kernel oops. I also tried, in Xenial, linux-image-4.4.0-2-generic and that failed. Setting /proc/sys/net/ipv4/xfrm4_gc_thresh to 5 causes the failure almost immediately. I would like to confirm my procedure however. I've been changing /proc/sys/net/ipv4/xfrm4_gc_thresh inside the containers, not the host.
