Failed to create task for container: ... device or resource busy

Docker Engine General
1

Hello,

After a while running my containers just fine it seems like I can’t restart a container anymore. After removing a bunch I can add again. So looks like some kind of cgroup limit.

Error response from daemon: failed to create task for container: failed to create shim 
task: OCI runtime create failed: runc create failed: unable to start container process: 
unable to apply cgroup configuration: mkdir /sys/fs/cgroup/docker/
431b39d05bc18f644bf4d61dab0d12997e1a45d2a209e9edd0604edb0b6047a2: 
device or resource busy

Any ideas how I can fix this?

Versions:

  • Engine and client: 28.0.4 (API 1.48)
  • Gentoo Linux amd64
  • containerd: v2.0.5
  • runc: 1.2.6
  • docker-init: 0.19.0

Thanks,
Milo

Not the same, but could be related Cgroup error on container creation

But I also noticed you are using containerd v2.0.5 whle containerd is still v1.7.x when installed from the official repositories. I have no idea if it has anything to do with containerd, but Gentoo is not officially supported by Docker so I assume Gentoo has its own Docker package.

Regrdless of the OS, unfortunately I don’t know how creating /sys/fs/cgroup/docker can be lead to that error message. The folder doesn’t exist on my machine (Ubuntu Noble) using CgroupV2.
