A problem of running shape_optimization.py in parallel due to error '139'

I have same problem. In cluster, I can run normal analysis (not optimization) without any issue. When I try to run optimization on nodes of HPC, it gives same error at random stage. For example sometimes at DNS2 Defrom or DSN1 adjoint.
Could you suggest any solution?

I managed to solve the error on my own. The problem was resolved when I made the following changes to the MPI parameters.
mpirun --mca btl_openib_cpc_exclude rdmacm --mca mpi_leave_pinned 0 --mca btl_openib_allow_ib 1 --mca btl openib,self,vader -n $NSLOTS
