Have you tried running hobbitd_rrd with the "--debug" option??  Add it to
the various hobbitd_rrd entries in server/etc/hobbitlaunch.cfg.  I haven't
tried it myself, so I don't know how verbose it gets.  I seem to recall
Henrik saying it's OK to just kill hobbitd_rrd processes because they get
respawned.

I guess the debug output shows up in the rrd-status.log in your Hobbit logs
directory.  Is there anything interesting in that log already??  Or any
other log??
