Further investigation seems to indicate that these events should be handled by "mcelog" or "mced". However, there is no /var/log/mcelog, nor do I have a "mcelog" or "mced" binary, nor does yum seem to contain anything related (based on "yum whatprovides '*/mcelog'" and similar queries). Thus, I still don't know what to do with these errors. Ignore them? I am running 32-bit CentOS 6.4 (legacy software reasons). -G.
