Right, thanks.

stat for /mnt/test/yp failed
ernno: 75 (Value too large for defined data type)

But why does stat64() on a 64-bit kernel tries to fill in larger data than on 
a 32-bit kernel and larger data also only for nfs-mount points? Hmm, I will 
tomorrow compare the tcp-packges sent by the server.


Many thanks,
