Docker is preventing system reboot

Hi,
I have a headless arch vm under proxmox for my homelab. I noticed that if i try to reboot it, either with "sudo reboot" or with the reboot option in proxmox, it hangs forever ( or for more that i have the patience to wait) with the message that a process with a certain pid is not stopping (sd-close). After a bit of investigation i found out that the hung process is related either to docker.service or docker.socket, since if stop them it reboot just fine. I would like to be able to reboot the machine without manually stopping those services first, even if there are several containers running, because it is useful to do so from the proxmox's interface from time to time.
Here's docker.service:

└─> systemctl status docker.service
● docker.service - Docker Application Container Engine
     Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; preset: disabled)
     Active: active (running) since Sat 2024-06-08 09:59:56 CEST; 13min ago
TriggeredBy: ● docker.socket

   Main PID: 606 (dockerd)
      Tasks: 314
     Memory: 272.6M (peak: 276.9M)
        CPU: 3.598s
     CGroup: /system.slice/docker.service
             ├─ 606 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock

             ├─ 997 /usr/bin/docker-proxy -proto tcp -host-ip :: -host-port 8000 -container-ip 172.17.0.3 -container-port 8000

and here's docker.socket:

└─> systemctl status docker.socket
● docker.socket - Docker Socket for the API
     Loaded: loaded (/usr/lib/systemd/system/docker.socket; disabled; preset: disabled)
     Active: active (running) since Sat 2024-06-08 09:59:52 CEST; 16min ago

      Tasks: 0 (limit: 38495)
     Memory: 0B (peak: 256.0K)
        CPU: 1ms
     CGroup: /system.slice/docker.socket

Re: Docker is preventing system reboot

Did you enable live-restore?
