This looks like a corrupted RRD file.

There are several potential reasons for this, but right now you should just take my word that it's harmless.
I am also having some trouble with a lot of NAN values in the disk history graphs. I'm wondering a) how to fix these errors, and b) if the errors have anything to do with not getting good data in the graphs.
What's the load on your server ? I've seen this happen on my own system, where it turned out that the amount of RRD file-updates was pushing the disks beyond capacity. vmstat/iostat data usually picks this up. But then, this would affect all types of graphs.
