[Wien] problems in optimize

[白宇]

Dear wien users:
     When I'm doing optimize proceure, after succesfully runlapw in two changed position in the changed volume struct, the following error happened, however there is no date in any *.error files, so would me please tell me how this happened and how I can solve the problem.

my optimize.job is:

foreach i ( \

                                       symetry_vol_-10.0  \

                                       symetry_vol_-10.0  \

                                       symetry_vol___5.0  \

                                       symetry_vol__10.0  \

 )
     cp  $i.struct symetry.struct

      x dstart -c

      min -I -j "run_lapw -I -p -fc 1.0 -i 40 "
     set stat = $status

     if ($stat) then
        echo "ERROR status in" $i
        exit 1
     endif

     save_lapw  $i

 end


the STOUT file is: (only the last two cycle)
