Dear all
I used input file for supercell with gamma and gamma-shifted k-point for using in sax. I used 32 node each contain 32 core . The number of bands is set to 1024  . The problem is  espresso can safely run pw1.in with shifetd 1 1 1 0.5 kpoint , but fails with error for run of pw2.in with 0 0 0 0.5 kpoint. The only difference in pw1.in and pw2.in is in thier k-points. the error is known is mailing-list :
 task #       952
     from  pzpotrf  : error #        47
      problems computing cholesky decomposition

This is very strange because when I set nbnd=512 the pw1.in and pw2.in run without any problem .
Can any one help me what can I do to remove the error ?
