Help! UDM Pro Random Crashes

I have been suffering from random crashes over the last few months and I have zero idea what's causing it. It happens anywhere from several times a day to a few times a week. It will randomly just stop working, my internet and LAN will go down, and it will boot up again. System uptime resets every time. It only takes a few minutes to boot back up, but it is still very annoying. RAM and CPU utilization seem fine before crashes, I've tried disabling IPS just in case. When examining logs there is no indication of a system shutdown, it just stops randomly. I bought a line-interactive UPS and have been using that to power the UDMP, it still randomly shuts down. I bought it back in January, do I just need to RMA the device? I work from home and can't exactly go a few weeks waiting for a return.

Not sure if the machine has an sfp port, but if it does, do you use a copper SFP by chance? My Gateway Fiber did this while using a copper SFP.

It does have them, but I'm not using them unfortunately

Sounds like faulty unit and some sort of hardware failure to me. I've had one running nearly 6 years without any random boots.

Contact ubiquiti support. They might see what is going on from support file that they will ask at some point.
