Hi William,
Thanks for attaching your results files; yes, everything in the short run looks normal.
It would be even more helpful if you could attach the results from your failing run, so we could find inconsistencies.
Have you previously completed a 10800 second run with 1 or 2 tiles, or was this your first time to do a 10800 second run?
Secondly, did you try a second run after the run with problems? If not, I would recommend rebooting all clients (incl the prime client) and VMs and running 10800 seconds again.
Thanks,
Rebecca
