Hello,

I have an nfs server who exports some backup directories for the lan's
users, it's a new install.

First I would like say that's not an hardware problem, because we have
no problem to use appletalk, ftp, ...

I can mount remotly a partition on the nfs server without problem but
when I copy something on it, the client ('cp' in this case) hangs, and I
receive these messages on my console :

nfs: task XXX can't get a request slot

where XXX is begin from 1 to...

When I look on the server, the file I was trying to copy is only 8192
bytes :

-rwxr-xr-x    1 root     root         8192 May 13 16:56 bash

After looking web, newsgroup, etc.. I've tried all what I can do to
optimize performance (wsize=8192,rsize=8192,hard/soft, etc.. etc..)

The only changes is when I use wsize and rsize to 8192, the file I sent
to the server can goes to 16384 bytes, but never more..

This is a LAN of ~ 10 computers, 100mbps, and we use switchs.
The servers and workstation use Debian woody, nfs kernel and user server
tried, same results.

Any type of help is welcome.

Thanks.
