The log except was from rrd-status.rrd, so from the hobbitd_rrd process.  We
have two physically separate Hobbit servers, on two physically different and
non-connected networks.  Let's call one of them Hobbit A, and the other
Hobbit B.  I first noticed a few graphs on Hobbit A were showing artifacts.
This was happening for a few hosts, and of those hosts, only a few of their
trend graphs, and not always the same trend graphs across the different
hosts.  I then noticed that the same thing was happening on Hobbit B.  Now
it appears more graphs are being affected on Hobbit A (I don't know about
Hobbit B, as A has the most monitored hosts, and so I'm first concerned with
that machine).  Graphs that were previous unaffected are now being
affected.  They are all showing the same symptom.  That is, spikes of data
with the exact same number:
5177668251... (it's a very big number, at least 50 digits).
