network.inteface.in.bytes problem

["Siekas, Greg" <greg.siekas@xxxxxxxxxx>]

I noticed something odd when using pmchart.  It displays ever increasing
bytes when displayin network.interface.in.bytes.  It's now in the TB
range and growing.  I'm using pcp 2.9.0 and pcp-gui 1.4.4.

pminfo on the system shows the following .

network.interface.in.bytes
    inst [0 or "lo"] value 513781
    inst [1 or "eth0"] value 1825297261184
    inst [2 or "eth1"] value 1589361196791
    inst [3 or "bond0"] value 3414658457975

Have these values overflowed something?

thanks,
Greg
