netstat statistic problem

Hi,

I just discovered a problem with hobbit and netstat statistics. It seems that hobbit cannot handle values greater than 2^31. When I look at the netstat graphs of some of our hosts, the values of the in and out packets suddenly fell down to zero. When I call netstat -s on the hosts, the number of segments received or send out are above 2^31. The graphs from hosts where the values are below this limit are normal.
