>Description:
When I use systat -ifstat, the Total counter gets reset around every 4th GB worth of data. No matter what, the counter will never show more than 4GB.

A friend of mine tested it on amd64 machine, and it does not happen there. He then tested it on his i386 machine and the Total counter got reset, too. I am not an expert but it seems like a bug.
>How-To-Repeat:
Just watch out the output of systat -ifstat
>Fix:
Sorry, I'd love to but I am in no position to do that. Thanks in advance!
