I looked at the source code and it seems On a system that I have access to with GigE cards, running constantly over 200Mb/s, the netstat -i counters will overflow on the order of once every minute or two. As an aside questions. When we update the network interface to use the larger 64bit counters, will external programs like SNMP be able to function with the larger sizes or will these have problems. I am not sugesting we don't do this, I just want to know. Jim -- /"\ ASCII Ribbon Campaign . \ / - NO HTML/RTF in e-mail .
