Ok, here's where that -vv switch can come in handy. Try again from the  
command line with -vv, and send the output you get. That should help  
me with the debugging. As it is, the only thing I would note is to  
wonder if you really want the critical and warning values to be 3 Gbps  
and 5Gbps. It's not completely unreasonable, of course, depending on  
what you are monitoring (I think there are devices that can get multi- 
gigabit speeds), but most devices never get anywhere near that kind of  
traffic. Regardless, that shouldn't cause the first errors you are  
seeing, as the lines referenced are just seeing how big the input  
values are. Course, if you ARE getting gigabit speeds, I suppose it's  
possible i'm getting an overflow somewhere- i've never tested with  
that level traffic (as I don't have anything that generates that kind  
of traffic).
