I got it ---

With the following entry in -etc-exports:

     /tank/t1 -maproot=0:10 -network 192.168.0/24

the NFS server crashes when /tank/t1 is zfs system.

With the following one:

     /tank/t1 -maproot=root -network 192.168.0/24

it works fine.

Mind you, '-maproot=0:10' is the first example from 'man exports' ...
