does the problem persist after you reconnect the network cable?
what happens when the server becomes available again?
are you mounting with UDP or TCP?

no. If server is available again, the process wakes up from D.

But like man mount says:
[snip] The process cannot be interrupted or killed unless you also spec=
ify intr. [/snip]
The process should be killable while the cable is pulled.
But that's not the case, although intr is in fstab.

uh. How to find it out? :)

I'm using intr.

kill -9 doesn't work for me to kill the app.

I didn't say kill the app. I said signal it with -9, then signal
rpciod.

Cheers,
