I updated my Plex after I saw this issue arise, but last night I see bandwidth spikes varying between 5-12 GB. Nobody was streaming anything, and I am confused why it would do this.

Was it during the times you have set to run the scheduled tasks? If so it could have been refreshing metadata content for your libraries.

It did fall between that time, but are bandwidth spikes of that size common? I haven’t seen that ever happen before in my Plex bandwidth history.

Is this something I should be concerned about?

Not sure but could be. You mention you upgraded plex so maybe a library refresh metadata was needed and depending on the size of your libraries that could be a lot of contention to update.
I’d suggest monitoring over the coming days and see if it stabilises.

Will do! Thank you! worst case scenario is there anything really bad I should be wary of? My plex just consists of movies I have burned from my personal collection and I only have family members added to it. I can’t imagine anything bad is happening, but I just want to be prepared.

Not really assuming your plex is running okay. Just the usual maintenance stuff. Scan libraries, clean bundles, empty trash and optimise database.

Spikes that high merely show that your server has lots of RAM. It is accessing media over network protocols which appear to be stored on the same machine.
Is machine virtualization involved here?

Machine virtualization is not involved. I use a Synology NAS if that helps. It is strange that it has happened now as opposed to when I set it up nearly a year ago.
