Hi All,
Having a strange issue with the graphs displaying what seems to be 50% of the
actual values (during 10 minute window) every 50 - 55 minutes.
Below are 3 images of flows / protocol TCP for;
1) showing all 10 routers

2) 8600 02 router

3) 8600 152 router

Looking at the timeslot statistics for the time slice shows the graph marker is
around 50% of the true value.
If I do a nfsen -r live all, eventually graphs are redrawn and show the correct
data.
Attached an image showing example 3 from above but after the -r live all. Can
see the dips in the graph are gone showing correct graph.

It's a Ubuntu 12.04 Server sitting on a VMware cluster running rrdtool 1.4.7,
nfdump 1.6.10p1, nfsen 1.3.6p1 and nfsight beta 20130323.
Anyone seen this behaviour and know how to resolve?
