Have you already tried to connect the server and one client directly? So using 
a cross-over-cable from the server to one client without any switch between.

Also, is your network really full-duplex? You can figure out using mii-tool.

I would also try if the same problems happen on non-root-nfs clients. So e.g. 
exporting only /usr and /home from the server, using a local 
linux-installation on the client and import those two directories.
Btw, I think I saw in one of your mail, that you are using 4096bytes for rsize 
and wsize as default, setting this to 8192 should increase the probability to 
see the problem occuring faster. I guess later on (when everything is 
working) you won't like to use 4096byte anyway.

Cheers,
	Bernd
