Possibly fixed.  There is possibly a bad entry in the nscd cache.
Restarting nscd did not solve the problem until I changed /etc/nscd.conf
from: enable-cache            hosts           yes
to:   enable-cache            hosts           no

I am not sure why restarting (machine and/or nscd daemon) did not clear
the cache.
