Are you sure you don't have other daemons like systemd-networkd or something else active which are racing with NM? From logs it is pretty clear that NM is sending exactly one router solicitation at: May 25 15:42:55 server.example.com NetworkManager[10973]: <debug> [1558813375.1729] ndisc[0x55a336c550e0,"enp2s0"]: router solicitation sent However it could be that NM is configuring the kernel in a wrong way.
I see from the log that you set a IPv6 token; can you please try without it if it makes any difference?But that machine needs to have a predictable, easily remembered address, which it does not get without a token. In any case, as a debugging step, I did disable it and restart NM and the storm did not start up with it. When I re-enabled the token again and restarted NM, the storm started when it started, so it does seem to be related to using a token.Also, please attach a log from the beginning of the profile activation.There is no "profile activation" because this is a headless server, hence the reason for the token. I'll attach the NM log from the time it is started up. Hopefully that provides what you are looking for.
Yes, it is ok. Note that you can force a new activation of a connection with: nmcli connection up $con_name where $con_name if the name of the connection obtained through: nmcli connection show In your case the connection name is equal to the device name - enp2s0. The reactivation is useful to apply changes after modifying a connection without the need to restart NM or reboot. Can you also attach the output of nmcli connection show enp2s0 ? Beniamino
