I never had such a problem on any installation.  Ones a rrd file is created, 
it is also updated.

Can you check if you have the needed processes running ?

"ps -ef | grep hobbitd_rrd" shows 4 processes on my box (lines are truncated):

hobbit   17554 17534  0 16:39 ?        00:00:05 
hobbitd_channel --channel=status --log=/home/users/hobbit/server/log/rrd-status.log 
hobbitd_rrd --rrddir=/home/users/hobbit/data/rrd
hobbit   17558 17534  0 16:39 ?        00:00:00 
hobbitd_channel --channel=data --log=/home/users/hobbit/server/log/rrd-data.log 
hobbitd_rrd --rrddir=/home/users/hobbit/data/rrd
hobbit   17559 17558  0 16:39 ?        00:00:16 
hobbitd_rrd --rrddir=/home/users/hobbit/data/rrd
hobbit   17564 17554  0 16:39 ?        00:00:43 
hobbitd_rrd --rrddir=/home/users/hobbit/data/rrd

You can also trigger an error by making the rrd files unwritable by the hobbit 
user.  This should put an error in the server logfiles whenever hobbit tries 
to update the rrd files.
