Segmentation Fault, NanoPi Neo Air

Question

Armbianmonitor:

I have gotten Oops a few times, now this morning I got it again I can see that is says "Segmentation Fault". I could still issue sudo armbianmonitor -u so I included those logs. Since I was also connected to both via SSH, where I was running "armbianmonitor -m" and logged in via serial I include the output of those windows below:

 

SSH output:

I don't know much how to read these log files and outputs so any help in understanding them would be appreciated.
