This is pretty strange since I'm doing the same thing but I don't get any 
spikes.
I just take the inoctets through snmp form my network interface..
Every night I turn off the machine and I think that part could be 
considered a rollover for rrdtool
but there are no spikes...
So I wonder why you DO have a spike..

Anything special you migtht be doing with making the graph?
