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.

Regards,
Dirk

You're right, there's an "atol" conversion that shouldn't 
happen. On 32-bit systems like most Intel-based systems, that 
is bad.

Will fix ...
