It's pretty much all the graphs, GAUGE or not. We upgraded our rrdtool as
we were on an older version and it seemed ok for hours but then in the AM
there were some massive spikes and it has spread like wildfire and we are
back where we started.  Not all graphs are affected though. It seems random
but it's probably not.
Still looking at stats and graphs for the vm from inside and out. Very
frustrating all this!
Thanks

Well, this is interesting.  The "max" is set at 100%, but rrdtool accepted
a value of 7921%.

I've had this happen in the past, but haven't found the cause.  I ended up
doing an xport/edit/restore on each RRD file affected.  However, it's only
happened here and there.  I've never seen a widespread problem across lots
of graphs all at the same time.  My first thought was a counter-wrap
problem, but as I recall, I quickly eliminated that as a possible cause.

Are all affected graphs of type GAUGE?
