CLUSTER_SPARSE_SOLVER segmentation fault

Hi all!

I am getting forrtl: severe (174): SIGSEGV, segmentation fault occurred during factorization step of CPARDISO. It happens when i try to solve Nonsymmetric system of ~ 8.5 million equations. It usually occurs when factorization is complete at about 80%. Everything is fine if number of equations is ~ 1 million.

My setup phase is

    NRHS = 1
    MAXFCT = 1
    MNUM = 1
    IPARM(1) = 1 ! NO SOLVER DEFAULT
    IPARM(2) = 3 ! FILL-IN REORDERING FROM METIS
    IPARM(4) = 0 ! NO ITERATIVE-DIRECT ALGORITHM
    IPARM(6) = 0 ! =0 SOLUTION ON THE FIRST N COMPONENTS OF X
    IPARM(8) = 2 ! NUMBERS OF ITERATIVE REFINEMENT STEPS
    IPARM(10) = 13 ! PERTURB THE PIVOT ELEMENTS WITH 1E-13
    IPARM(11) = 1 ! USE NONSYMMETRIC PERMUTATION AND SCALING MPS
    IPARM(13) = 1 ! MAXIMUM WEIGHTED MATCHING ALGORITHM IS SWITCHED-ON (DEFAULT FOR NON-SYMMETRIC)
    IPARM(35) = 1 ! ZERO BASE INDEXING
    ERROR = 0 ! INITIALIZE ERROR FLAG
    MSGLVL = 0 ! PRINT STATISTICAL INFORMATION
    MTYPE = 11 ! REAL UNSYMMETRIC

I use

mpiifort for the Intel(R) MPI Library 2018 Update 1 for Linux*
Copyright(C) 2003-2017, Intel Corporation.  All rights reserved.
ifort version 18.0.1

My compilation line is

mpiifort -o mpi -O3 -I${MKLROOT}/include -qopenmp MPI_3D.f90  -Wl,--start-group ${MKLROOT}/lib/intel64/libmkl_intel_lp64.a ${MKLROOT}/lib/intel64/libmkl_intel_thread.a ${MKLROOT}/lib/intel64/libmkl_core.a ${MKLROOT}/lib/intel64/libmkl_blacs_intelmpi_lp64.a -Wl,--end-group -liomp5 -lpthread -lm -ldl

I tried to run on cluster on 8 nodes.  Each node has 2x Intel(R) Xeon(R) Gold 6142 CPU @ 2.60GHz and 768Gb of RAM.

I also leave here link to my matrix in CSR3 format. Attention: unzipped files are more than 2 Gb.
