nfs: server ipaddress not responding, time out

[Javier Perez]

Hi
I had to unplug the ethernet cable from the nfs server.
After I plugged it back, the client machine is filling my journal with the
following message

nfs: server "ipaddress" not responding, time out

where ipaddress is the ip address of the nfs server.

I did a lazy unmount of all the shared directories, but I am still getting
this message.
If I try to use Thunar, it will not open up and even the panel will not
accept a click. I can  switch windows  with ALT+TAB

How can I find out whatever process is still trying to reach the nfs
subdirectories and kill it?

Last time this happened I had to reboot the system. I do not want to do it
again

Thanks

JP
