I'm almost certain I have enough memory - 32GB on a machine that really 
is not doing anything very memory intensive.  (Samba, dovecot, plex, 
foldingathome, etc.)  And I have a 4GB swap file.

Yeah that thought occurred to me as well.  I ran a quick memtest86+ when 
I first built the computer and it didn't show any issues.  But perhaps I 
should take some downtime and have it run one through the full 3 rounds.
