The 600 is the value for 'heartbeat'. From rrdcreate(1):
heartbeat defines the maximum number of
seconds that may pass between two updates of
this data source before the value of the data
source is assumed to be *UNKNOWN*.
Make heartbeat allways bigger than step, maybe 4000 in this case.
(Maybe rrdtool shouldn't accept heartbeat settings lower than step?)
