my unraid server halts suddnly

[unraidnt]

Greetings.
I have a weird problem that happens to my server, just out of a sudden everything freezes and I can not do anything!
I cant browse the server via the web (address unreachable) still there is CLI/GUI output through VGA monitor but nothing moves and I can't do any interaction.
the network interface goes down, and I cannot ping the server nor I can see it connected to the switch.
even using the IPMI console same thing freezing screen.

basically, a dead HW, unless I do a hard restart.

 

this happened maybe 6 or 7 times and I was ignorant enough to not save the log to the USB, but this time I did.
I'm not an expert but the log says something secondes before the problem happened, see the logs from this time and onward Oct 19 05:40:52

 

I suspect the problem is related to the UPS, cuz I unplug its USB from the server for almost 2 weeks and nothing happens during this time, but when I plug it again the problem came back just around 48hrs after.

 

I'm running the latest Unraid using supermicro X9SCM with xeon E3-1265L V2
