System Reset Exception -- Reset due to FatalError

I have a PTP 450i link that I use for a backup to our licensed link.  It has been rebooting on its own and the message in the error logs says "System Reset Exception -- Reset due to FatalError" "please contact Cambium Support".  

I have the ethernet disabled in the master so that I can manully enable it when I need it if I'm doing maintenance on the licensed link, etc.  Would this be causing this?  Does it about every 2 hours.  

 

How did you resolve this? I am having a similar situation

What firmware are you running on the radio?
