[Nut-upsuser] [Eaton 5S 1500] overvoltage shut down?

Spike spike at drba.org

Hello Charles,

I've attached a dump below. There were no long entries on any of the hosts,
neither the one running standalone, nor the master/slave combo, which is
not too surprising, it was really fast: I saw the light flickering in the
room, almost like flash, and all those 3 systems went down. I first heard
the "click" of the ports being disabled, heard the systems shut down, and
then the louder click of the UPS turning itself off. Probably less than
3secs in total.

This is on ubuntu xenial. The servers have dual power supplies, total 4
ports, plugged into the battery backups + surge protection ports on the
right hand side. Eco mode is disabled.

thank you for your input,
