Getting frequent "NaN" gaps in graphs, yet data is being retrieved ok

I've been using cricket for around a decade.

In the last few years, we've grown to the gigabit ethernet level. Since 
then, we've been getting strange gaps in our graphs, with NaN listed as 
the current value if you look at the graph when the gap is occuring. It 
doesn't seem to be based on a traffic level threshhold...I'll see valid 
data displayed at times that are higher usage than the traffic rates when 
the data is NaN.

Whenever I run a manual collector, the data is being retrieved fine. I 
can't figure out why the data isn't being displayed properly, and I'm not 
able to think of a way to troubleshoot this further. I've tried specifying 
the speeds of the interfaces, and I've even tried doing a fresh install on 
a much more modern server (as the server cricket has been on since 2004 is 
still chugging along, and producing graphs a bit more slowly than it 
should).

Any suggestions?

Thanks,
Andy
