I believe I have a valid license, but I am unable to keep the server up and running.

Near immediately after startup, I see this warden.log:

Check logs at: /opt/mapr/logs/nfsserver.log]

However, nfsserver.log is empty.  I've tried turning up the logging level in nfsserver.conf to DEBUG, but I'm still no getting anything.  Thoughts or suggestions?
