Those are good questions to answer because they point either to non-determinism in the CPU or host state leaking into the simulation. Another thing people suggested way back when when I was trying to fix something similar was to use netcat with tracediff to compare execution across two known different machines. For a long benchmark I'd suggest finding something to keep you occupied while it runs, maybe a quick trip to Europe for instance, but eventually it might tell you what's going on.
