The scan was retried with nothing else running and after a fresh boot.
RAM use never went above 6G on a 32G system. Attached is the
screenshot of the crash.

I can breack the 172.16.0.0/12 scan into 4 parts of /14 each, however
when it comes time to do the 10.0.0.0/8 scan breaking into units of
/14 will take forever in terms of human monitoring and intervention.

Let me know if I can enable any debugging or logging features to
assist in resolving this. I am happy to help any way I can..

You will be better off, in this case, using the command-line Nmap rather
than Zenmap for these big scans. Zenmaps keeps information about the
whole scan at once in memory, while Nmap uses only enough memory for a
few thousand hosts at a time. You can save the results to an XML file
(-oX option, http://nmap.org/book/output-formats-xml-output.html) and
open the XML in Zenmap later, after the scan is finished.
