setup a large MRTG/RRD system (30K) graphs with a mixture of devices. One set
of devices seem to be giving me issues. The graphs have spikes in them seemingly
in the same places throughout the graph. I have checked all that I know to
check and am appealing to you for suggestions.<o:p></o:p></span></font></p>

system this is running on is a dual Xeon @3GHz with 8GB of memory and four SCSI
U320 drives in RAID 5. It is connected to the network via a dedicated 100Mbit
line. I have attached an image of one of the graphs and also sent it to
imageshack here:<o:p></o:p></span></font></p>
