Dear all pwscf users,
               I am running a calculation for an isolated Mn(IV)-Mn(IV)
bimettalic system, using the pseudopotential for Mn (from pwscf.org website)
      Mn.pbe-sp-van.UPF
     Perdew-Burke-Ernzerhof (PBE) exch-corr
     semicore state s in valence
     semicore state p in valence
     Vanderbilt ultrasoft
all other pseudopotential is also taken from pwscf library, this system has
+4 charge the detailed input is given below,This calculation is terminating
by showing *the eroor message*

     Self-consistent Calculation

     iteration #  1     ecut=    40.00 Ry     beta=0.70
     Davidson diagonalization with overlap

 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     from  pzpotrf  : error #       358
      problems computing cholesky decomposition
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

when I was checking the forum for similar error I saw Dr Giannozzis mail,
according to that I am providing the details, I am sorry if I have missed
any

*Details of machine* where I ran the calculation ( i also have checked the
disk spaces)

CPU -Intel Xeon
OS- Platform 4 / Redhat
MPI- mpich2-1.0.5p4
I am using 16 processors
npool=4
