Has anyone seeing cacti displaying large bandwidth utilization values for interfaces of Cisco Nexus 7K devices?
I've a large cacti setup running v 0.8.8a with boost plug-in. There are couple of devices which are showing bandwidth utilization values going over 641625880.82%. Weird part is the same device and interface is being graphed on two separate cacti instances, with the same data, graph templates, one instance shows correct BW utilization values, other one displaying these large numbers for reason unknown.
I enabled the debug and can see that polled SNMP values are correct for the interfaces, but still cant figure out what one instance shows large values and other one shows just fine. The only difference between the two instances is boost plug-in is enabled only on the instance with incorrect BW values.
Debug data below.

Not sure why spikes are seen for the above data.
