More to this:
I see a message from from exportfs:

exporting oren:/ftp
exporting oren:/ftp to kernel
oren:/ftp: Invalid argument

then after man reading i notice that due file file /var/lib/nfs/xtab has 
zero length, then
i try manually
  exportfs -av
and get the among normal messages for all expors again
  ....
  oren:/ftp: Invalid argument
this time /var/lib/nfs/xtab has real content, except of course missin 
entry for oren:/ftp
