It was also discussed in:
http://lists.freebsd.org/pipermail/freebsd-current/2007-July/074495.html
where it was found to be caused by lseek behaving differently on ZFS:
http://lists.freebsd.org/pipermail/freebsd-current/2007-July/074584.html
And one person found a work arround for ZFS by removing the
repdir_get* sources from samba:

http://lists.freebsd.org/pipermail/freebsd-current/2007-July/074601.html
Here is a test program thats shows some problems with the consistency
of telldir/seekdir behavior:

Read the full thread to get all the information on the problem.
