On one of my servers I’ve observed an issue with LXD service twice. The processes get hung up for some reason inside the container and then if I try reboot from within the container or stop/start from server, the container just hangs.
LXC stop command is hung up for a while with no response on the terminal… I ended up rebooting the server to resolve this but I need a solution to resolve this permanently. Kindly help.
OS: Ubuntu 18.04
LXD version: 4.21 (installed with snap)
I ran the following command to see the logs:
sudo cat /var/snap/lxd/common/lxd/logs/lxd.log
Observed this error log:
t=2022-01-05T17:21:21+0000 lvl=eror msg=“Error calling 'lxd forknet” err=“Failed to run: /snap/lxd/current/bin/lxd forknet info – 3865 -1: Failed setns to container network namespace: No such file or directory” instance=q457c0cc5109a instanceType=container pid=3865 project=default
Any suggestions on what this error message indicates?
Lxc container show log info gave the following information:
