I am doing something like this:

FreeBSD zfs -----nfs mount -------> Linux machine -------smb
mount-------> whichever client

Note I am using NFS from FreeBSD instead of samba.

And before I added this to the linux machine's smb.conf global section,
I would get total lockups and nobody could list directories.

    strict locking = no
    blocking locks = no

So give that a try.

With the first setting, any tests I tried worked fine, but others
reported a similar problem, maybe when there are a few concurrent users.
With the second setting, I haven't had the same problem since. (But if I
share my .zfs directory over NFS, listing that hangs the dataset)
