[rrd-users] Rollover problems on high bandwidth?

I'm using RRDTool 1.0.7, MRTG 2.8.8, gd-1.6.2, libpng 1.0.3, and zlib 1.1.3
on Solaris 2.6 with perl 5.004_04 and the latest version of 14all.cgi. 

I am polling an ATM OC-12 interface on a Cisco 12012 router which is
passing ~300 Mbps and has been for about 40 minutes. However, my 14all
graph is showing a max traffic rate of 121 Mbps and current usage of 80
Mbps. However, when I look at the interface stats, I clearly see over 290
Mbps. Any idea why this might be rolling over? Is anyone else running
traffic at these rates?
