HSE and spin-orbit coupling together are not working.

I am doing the band-structure calculation for Ge using HSE and spin-orbit coupling (SOC). With HSE or SOC (with PBE) alone, it's working and give correct band-structure. But when I try to do with HSE potential with SOC - on the job gets killed.

For HSE:
1step: I do normal DFT-SCF calculation with IALGO = 53
2step: I continue the job with the WAVECAR file obtained in the 1step.

FOR HSE+SOC:

1step: I did normal DFT-SCF calculation with IALGO = 53

System = Ge

ISTART = 0 job : 0-new 1-cont 2-samecut
ICHARG = 2 charge : 1-file 2-atom 10-const

Electronic Relaxation 1
IALGO = 53
ENCUT = 450 eV
NELM = 60
NELMIN = 0
NELMDL = 6 # of ELM STEP m
EDIFF = 1E-05 stopping cretiria for ELM
MAGMOM = 2*1

LMAXMIX = 4
INIMIX = 0
AMIX = 0.2
BMIX = 0.0001
AMIX_MAG = 0.8
BMIX_MAG = 0.0001
MAXMIX = -12

Ionic Relaxation
EDIFFG = -5.E-03 stopping-criterion for IOM
NSW = 0 number of steps for IOM #
ISIF = 2
ISYM = 2
ISPIN = 2
IBRION = 1

DOS related values:
SIGMA = 0.05
ISMEAR = 2 broad. in eV, -4-tet -1-fermi 0 gaus

NBAND = 20

KPOINTS:
K Points : Autometic mesh
0 ! number of k-points = 0 ->automatic generation scheme
Monkhorst Pack
7 7 7 ! grid 10x10x10
0 0 0 ! shift (0,0,0 gamma point)

POSCAR:
cubic, Ge, lattice structure -diamond
5.6579 ! universal scaling factor
0.0 0.5 0.5 ! 1st Bravais lattice vector
0.5 0.0 0.5

2 !no. of atom per species
direct
0.00 0.00 0.00 T T T
0.25 0.25 0.25 T T T




2step: I submitted job after adding LSORBIT = .TRUE and SAXIS = 1 0 0
My INCAR file for the 2step is as follows:

System = Ge

Start parameter for this run:
ISTART = 0 job : 0-new 1-cont 2-samecut
ICHARG = 2 charge : 1-file 2-atom 10-const

SAXIS = 1 0 0
GGA_COMPAT=.FALSE.

I tried with existing WAVECAR which I obtained in the 1step then also it gave me error:

ISTART = 1
ICHARG=2 and with 0 also
ERROR: while reading WAVECAR, plane wave coefficients changed 1882

With this combination also job get canceled

==================================

Is it due to IALGO = 53 which is not working for SOC calculation. I found in the manual that for HSE one can use only IALGO = 53 or 58.

If anyone can suggest or tell me what is the problem. I'm using VASP 5.2 parallel version.
Is there any mistakes in my input file? Any comments and suggestions are appreciated.
