What's your hardware? E.g. we have a couple of 48-core supermicros that 
shipped with "balanced fan plan" in the bios and no thermal sensors 
under the memory banks on the motherboard. Guess what happened when they 
got going.

We have about 10 older servers of varying vintage running centos 7 
pretty much since it came out (tracking cr), and the current stable 
condor. No condor crashes that I can recall, nor any sig 6'es on any of 
them.
