How to restart a frozen LXD container

This article provides a How-to guide for restarting a container in a cluster with the LXD virtualization type. If the container is frozen, any actions on it will be blocked. For example, starting or deleting VMs.

To restart the container:

Connect to the faulty node via SSH.
Find the ID of the faulty process:
```
ps -eF | grep '<container_name>' | grep 'lxc monitor'
```
Comment
<container_name> — name of the frozen LXD container
Disable the faulty process with the command:
```
kill -9 <PID>
```
Comment
<PID> — ID of the faulty process

Double-check the process ID before disabling it. An error in the ID will disable the wrong process, which may cause the platform to work incorrectly.

After these actions, the container will resume operation. Perform the required action, such as starting or deleting a VM from the VMmanager web interface.
