Hi everyone,

Well, we lost power here again.  I was not at home, but I guess a dump truck smashed into some power poles and took out half the city; actually tripped most of the breakers in the panel.  Anyways, the power was out for just a few seconds and of course my servers shutdown on me after power being out for just a second or two.  Here is my syslog from two different machines.  I included everything just in case.

“Proton":  https://hastebin.com/uluqaqetuc.bash
"Plex”:  https://hastebin.com/apudatonun.sql

Let me know what you think.  I just tested everything over the weekend and it all worked perfectly; cut power and machines stayed up until it was time to shut them down (I temporarily configured them to shut down after 5 minutes so I didn’t have to wait for the entire battery to drain).  I seriously at am a total loss.  I guess HDD Hibernation was not the culprit either since I’m still getting the same results.   Ugh.  Thanks everyone for all your help so far!!!!!

> Roger's comment confirms my suspicion of NUT as provided by Synology. They make a great NAS product, but then they bolt on all manner of other things. In my opinion, best to leave the NAS as an appliance configured and managed by their GUI tools, and let it just be a NUT client rather than trying to configure it to be the NUT server. I use and find the RaspberryPi's to be very capable NUT servers with the rest of my systems (including my Synology NAS) as NUT clients. Much simpler to manage that way as you have complete control over a fairly current NUT as provided by Raspbian (a Debian derivative). The only kink I've run into is that the Synology NAS as a NUT client provides no means of changing the NUT credentials, so you have to use default credentials for NUT (another reason to make sure NUT is on a protected network).
