What I would expect you do see on the server if you do netstat -t is something like: Active Internet connections (w/o servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 elfman.orchestra.c:2049 dulcimer.orchestra.:800 ESTABLISHED The local address is "2049". The remote address could be anything. My 2.4 Linux clients seem to choose 800, but anything is reasonable. I would expect the see the Recv-Q and Send-Q jump around a lot when IO is happening, but settle to zero whenever it is quiet. If the connection that you are looking at is the NFS connection (i.e. the other end is 2049) then the fact that it never gets below 160 suggests that I've got my accounting wrong somewhere. The simplest option would be that sk_reserved goes negative, but I cannot see what would cause that...
