SPAM in syslog

Syslog is full of messages about network. This repeats every five seconds:

Obviously the log is not very useful with all that..

    It looks a lot like something is constantly bringing the interface down and then connman brings it back up. I don't get that myself on my board.

    Are you using the ubilinux 4 version?

    I see two network cards, so I assume this is an UP Squared board. As ollittm asked, please confirm it is the latest version of Ubilinux4 (I see it in the log, but not sure if it is beta or RTM). And I'll agree with WereCatf statement: I haven't seen these with my UP Square boards either.

    Something else to consider is your physical network: cables, network switch/hub, power supply, etc.

    Well:
    [email protected]:~$ uname -a
    Linux ubilinux4 4.9.45-ubilinux+ #2 SMP Fri Sep 8 10:51:36 IST 2017 x86_64 GNU/Linux

    At least it's the file available from downloads with apt updates applied. For what it's worth, I have RPi on the same switch not generating these errors. Instead it's spamming WLAN messages.. I haven't configured WLAN at all for UP^2 so it's not probably that.
