problems stability freebsd

I am having a problem with my Ryzen 7 1700 upgraded FreeBSD server. I recently upgraded two servers from older 6 core AMD processors to new Ryzen 7 1700 processors. Since replacing the hardware, the servers have been extremely unstable. Uptime between crashes ranges from just a few minutes to just under 17 hours. The older hardware was rock solid. This occurs on the two systems upgraded to Ryzen, so it is not a memory problem.

 

Hopefully I can find some help for this problem here.
