4.1.2 is a bit old; you should at least upgrade to 4.1.2p2 since there
are a couple of security related bugs in the original 4.1.2.

It doesn't affect the problem you have, though. Is this Debian 3.1
(Sarge) ?

That's a new one. What rrdtool version do you have ? "rrdtool --version"

Could you try adding the "--debug" option to the hobbitd_rrd commandline
in the ~hobbit/server/etc/hobbitserver.cfg ? It will then print out the
exact parameters it uses for creating the RRD files, like this:

2006-08-08 13:21:02 RRD create param 16: 'DS:tcpInUnorderPackets:DERIVE:600:0:U'
2006-08-08 13:21:02 RRD create param 17: 'DS:tcpRetransPackets:DERIVE:600:0:U'
2006-08-08 13:21:02 RRD create param 18: 'RRA:AVERAGE:0.5:1:576'

2006-08-08 13:21:02 RRD create param 20: 'RRA:AVERAGE:0.5:24:576'
2006-08-08 13:21:02 RRD create param 21: 'RRA:AVERAGE:0.5:288:576'

You could then try running the command by hand (just a few of the DS
lines are needed). E.g.

rrdtool create testfile.rrd \
   'DS:udpInDatagrams:DERIVE:600:0:U' \
   'RRA:AVERAGE:0.5:1:576'

and see if it gives the same error.
