I'm on a box with a fxp ethernet (2 of them), to a 100MB full-duplex hub, from there to a Network Appliance. I NFS mount the Netapp on many of my boxes, this is the only one that complains. The mail server running 2.2.5 doesn't complain, and the 3.0 boxes don't, just this one. The network interface has no errors, no collisions. The hub shows nothing wrong either. There's a pretty constant stream of data to the netapp, no pauses in netstat output that I can see. I'll bump nmbclusters, and see if it helps. I notice that I'm running nfsiod -n 16, and all the nfsiod's are accumulating CPU time. On some of the lesser pounded-on servers, the last 4-5 don't get any CPU time... Just to see if I'm going crazy, I rebooted the 3.0 box that was the old INN server, and plugged in the cables, and it doesn't have the problem at all. Just cranks along... I can always go to 3.0 I guess, the UP stuff seems pretty solid, but I'd rather stay on -stable on production machines.
