Your RRAs are applied over ALL DSs, not just the previous one.  So, you only
need to do this:

 

rrdtool create boiler.rrd \

--start 1325232008 --step 600 \

DS:boiler_out_flow:GAUGE:600:0:U \

DS:boiler_in_flow:GAUGE:600:0:U \

DS:vihara_in_flow:GAUGE:600:0:U \

DS:vihara_out_flow:GAUGE:600:0:U  \

DS:outbldg_in_flow:GAUGE:600:0:U  \

DS:outbldg_out_flow:GAUGE:600:0:U  \

DS:cistern_top:GAUGE:600:0:U  \

DS:cistern_bottom:GAUGE:600:0:U  \

DS:boiler_flow_gpm:GAUGE:600:0:U  \

DS:vihara_flow_gpm:GAUGE:600:0:U \

DS:outbldg_flow:GAUGE:600:0:U  \

DS:boiler_btu_per_hr:GAUGE:600:0:U  \

DS:vihara_btu_per_hr:GAUGE:600:0:U  \

DS:outbldg_btu_per_hr:GAUGE:600:0:U \

RRA:AVERAGE:0.5:20:10000

 

 

Possibly you have also hit a limit somewhere, but this is the first
irregularity that I noticed.
