[rst0git]

There is a race condition in docker/containerd that causes docker to occasionally fail when starting a container from a checkpoint immediately after the checkpoint has been created. This problem is unrelated to criu and has been reported in https://github.com/moby/moby/issues/42900

There is a race condition in docker/containerd that causes docker to occasionally fail when starting a container from a checkpoint immediately after the checkpoint has been created.

It looks like this problem has now been fixed upstream (https://github.com/moby/moby/pull/47456).
