DOS run fails

[abmo]

Hi,

I run DOS calculation for a Ni(111) surface. I do a SC run and then run DOS using the following settings:
for SC run:
ISTART= 0
ICHARG= 2
ISMEAR = 1
EDIFF = 1.00e-06
PREC = Accurate
LWAVE = .FALSE.
LCHARG = .TRUE.
ENCUT = 400.000000
IBRION = -1
NSW = 0
ISPIN = 2
NELM = 100

for DOS run:
ISTART= 0
ICHARG= 11
ISMEAR = -5
EDIFF = 1.00e-07
PREC = Accurate
LWAVE = .FALSE.
LCHARG = .TRUE.
ENCUT = 400.000000
IBRION = -1
NSW = 0
ISPIN = 2
LORBIT = 1
RWIGS = 1.4
NPAR = 1
EMIN = -20
EMAX = 15
NEDOS = 3500


I have done this for a 2*2*4 supercell successfully but when I tried to do exactly the same for a 4*4*5 supercell the DOS run failed with the following error. It would be appreciated if any body can comment on this.

when DOS running，set ISTART=1
