I meant there's no response from the nfs-server. I can interrupt the
»find | cpio« and restart it. When restarting directly after that it
will hang too, but if I wait for about 30 seconds and restart it, the
same amount of data is copied.

There's only one client and the server isn't busy.

I'll send you private email.

(Doing the same on an loopback mounted filesystem on the server itself
works fine.)

The problem with troubleshooting is that trouble shoots back.
