We have two Textronics X-Terminals that boot from files held on
an SGI server via NFS. whichever one is switched on first boots
up properly but the second boots very slowly and claims the NFS
server is not responding, it comes up eventually and then works
fine. It does not matter if the first is still booting or is up
and sitting quietly waiting for a login. If I unplug the
X-Terminal thats already up while the second is trying to boot
up it then speeds up.  I've used Ethereal to capture the packets
and I can see the UDP NFS packets coming back from the server
without delay, the X-terminal seems to wait between requests for
anything up to 10 secs. The same total number of packets go
across in both cases (3000 or so).  I've unplugged everything
else from the hub (this is a UTP network using a hub, not a
switch).  I'm completely stumped, any ideas?
