You should probably let the Snort people know that there is a false positive on your plugin usage tracking. I get hundreds of warnings about a sign of possible infection in my network. When I hunted down the details it's because of accessing plugin-usage.edacerton.win and there is a Snort rule that any access to a .win domain could indicate compromise. I don't know if they except specific domains like yours that are known to not be bad. Snort - Rule Docs: https://snort.org/rule_docs/1-44077 I turned off usage data collection, assuming that will clear up those warnings.

Update: Changing from the built-in ups support to NUT did, in fact, allow me to shutdown the system and have it power off properly.

I have the same issue. Every time I shut the server down it appears to close everything out but leaves power on just like you described. I did find I can shut it down totally from the command line using parameters to turn the system off. I also am using apcupsd so I'm guessing that's related. I configured the UPS settings in UNRAID to talk directly to my APC SmartUps 1400RM. I'm also running a NUT server that monitors all my UPSs so maybe I should check out NUT for UNRAID to see if I can make it work as a client. I'm pretty sure I tried to use NUT for UNRAID and it wasn't working for me but I'll try it again if it might solve this problem.
