unregister_netdevice kernel message after restarting container

[ivanjx]

im getting a lot of this kernel messages on my ssh terminal that says:

Message from syslogd@home-server at Aug 13 15:06:36 ...
 kernel:[614037.260262] unregister_netdevice: waiting for lo to become free. Usage count = 1

that happens everytime i restarted the transmission container. the message will only go away if i reboot the docker host. here is my docker daemon config:

{
    "dns": ["8.8.8.8", "8.8.4.4"],
    "ipv6": true,
    "experimental": true,
    "ip6tables": true,
    "fixed-cidr-v6": "fd00::/80"
}

Why have you blanked out the image name? For all we know you might not be using our container.

[ivanjx]

doesnt really matter but here you go: https://gitlab.com/ivanjx/transmission-flood/-/blob/master/Dockerfile

[j0nnymoe]

quick google shows that error is not related to our container but likely due to your changes in the daemon.json
