Hi, I install the lxd on Debian 9 using snapd with this guide (https://stgraber.org/2017/01/18/lxd-on-debian/) and create three containers. I configure the public ip’s using a bridge (macvlan) according to my server provider. The config of the container is (other containers are the same):
architecture: x86_64

The containers and host works well, but I have an strange problem with the network interface. I lost the connectivity with the server many times and randomly, every day. The kernel logs are:
Dmesg output:

I created a ticket on my hosting provider service and they did a hardware and cable verification, also they says to me that the traffic isn’t suspicious. When I reinstalled the host server, the problem did not happen before mount the conatainers infraestructure.
I do not understand what is causing this error.
I leave here some configurations and versions:
