The file remains empty.
I really don't know enough about NFS, but isn't that getattr message repeated
some seconds latter, and repeated... (even though it always gets an answer)
The ktrace is in http://mega.ist.utl.pt/~mlsr/ktrace.txt
I'm not sure it's good. I can't see cron.pid there.
I had to reboot to end the process, otherwise I couldn't kill cron and
the trace didn't grow either.

The tcpdump -w is in http://mega.ist.utl.pt/~mlsr/nfs.bin
