Hi Prof Blaha and Wien users,

     I previously wrote you about a problem I was having with band structure 
calculation of semiconducting
supercell with transition metal impurity when spin-orbit coupling is added. As 
you pointed out the mistake,
I resubmitted the job and, although it did not crash, this time it ran into a 
different problem. After running
the job for few hours the size of the files in scratch directory started to 
increase, eventually exceeding
100 Gb !! It doesn't seem reasonable to me since I have calculated the band 
structure of the same system
without spin-orbit coupling but otherwise with the same set of parameters and 
that worked out fine. Since 
it didn't produce any error file I am not sure where to look for the problem 
and how to fixed it. 

My system is a 64 atom GaAs supercell with only one impurity and I am using 
Wien2k_9_1 version. Only difference 
between the case of without spin-orbit and with spin-orbit is that the number 
of inequivalent atoms are 10
and 16, respectively. I should mention that the band structure with spin-orbit 
coupling of a regular GaAs cell
works fine. So it seems like the memory problem arising only with the 
spin-orbit calculation of the supercell
and I am not sure why it should eat up all the disk space in the scratch 
directory. Any suggestion will be
appreciated.

Thanks,
Fhokrul
