I published another post but I have investigated a bit and now I have more information. I'm running docker swarm on 5 nodes, one leader and six slaves. All the nodes have Debian Stretch with kernel 4.9.0-1-amd64 and docker version 17.03.0-ce-rc1 (last one). I'm running 40 containers on the slaves and, for some reason, swarm is restarting them very often. When a container is restarted in one of the slaves, the daemon.log shows this message: Feb 23 09:10:06 slave2 systemd-udevd18373: Could not generate persistent MAC address for veth0c959e1: No such file or directory Feb 23 09:10:06 slave2 systemd-udevd18374: Could not generate persistent MAC address for veth5539b9e: No such file or directory Feb 23 09:11:40 slave2 dockerd946: time='2017-02-23T09:11:40+01:00' level=info msg='Firewalld running: false' I see that there is a but, is this the only reason? Is anyone facing a similar problem?
SIOCSIFADDR: No such device SIOCSIFADDR: No such device eth0: ERROR while getting interface flags: No such device eth0: ERROR while getting interface flags: No such device I've googled it and found that it can be due to some issue with MAC addresses, but if i can not see the interface in the guest, then i can not change it's MAC.

We are runing UNMS on virtual servers with UBUNTU 16.04 LTS with eth0 and eth1 interfaces ( eth1 has public IP) After UNMS upgrade to version 0.13.1 server stop responding at all. Thank you for the report. Please describe into more details the symptoms of the situation. Do you get some error message from the restart command? What exactly means that networking is killed? You were unable to log into the server through eth0/eth1? Or just a ping was failing?
One more important thing is to check if the private address of the eth0 port doesn't collide with. Can you replicate the error and send me UNMS when the situation is in the process? Please, send the files to my email radek.skrivan(at)ubnt.com and include URL of this thread in the message.
