Are you sure the pflow device is set up correctly? Try just running
flowd in debug. Also make sure /tmp/flowpipe is not there before running
netflowdb. Finally, make sure your flowd.conf file is correctly setup.
One more thing, if you have any flowd daemons running, they'll conflict
with netflowdb.
