Though I am not sure what the console log indicates, it might be a power supply issue. Before in our office we had an iMac that would reboot by itself at random and it was traced to a faulty power supply. The power supply was replaced and the iMac was working fine after that. Try to observe further if this rebooting would repeatedly occur. That's a nice Mac Pro as I have used that machine.

Are you using ECC RAM now?

Non ECC RAM won't cause the problem, but it can rule out if that's the RAM's problem.
