Smoothing a bogus peak, was: graph rollover

Thanks for all help and suggestions,

thanks to you I have this going as intended, again;

however two of my graphs have registered a bogus peak
(I think when the data source was switched over to 64bit counters query)
(35Gbps in 5min avg graph, that propagated further to 30min avg graph
as 6.53Gbps, and to 2h avg graph as 1.63Gbps; normally spotted peaks
on these are 30Mbps on the 5min graph)
Is there a way to smooth this outstanding error out?
