:Beyond netstat -k, you can probably use lockstat or other kernel :profiling tools as I mentioned in my earlier post to give them a :good idea of where the bug really is. Interrupt issues aren't :always going to be cut and dried. There could be some particular :flavor of IOS, network adapter, media type, CPU, OS, etc. that :is more prone or less prone to the problem. One other thought comes to mind is that it could be a particular tty discipline or STREAMS issue at hand. The -network- may not be as much of a factor as "how does the particular traffic that ends up displayed on the telnet client interplay with the OS". I doubt that's the issue in this particular case, but you never know. I've seen a whole lot of stranger things... -- Mail: mjo@xxxxxxxxxxx WWW: http://dojo.mi.org/~mjo/ Phone: +1 650 933 9487 =--==--==--==--==--==--==--==--==--==--==--==--==--==--==--==--==--==--==--= "I was being patient, but it took too long." -Anya, the Vengeance Demon
