We strongly advise against re-exporting NFS imports via
Samba, this is asking for trouble on many fronts. You're
seeing one symptom of this. It might be the NetApp box, it
might also be flaws in the NFS client implementation, who
knows. Please enable the CIFS exports directly on the NetApp

If for some reason you can't, you might try "posix locking
= no" on the samba server.
