MPI Bus Error

I'm developing a MPI application, which relies heavily on the MPI shared memory. Recently, I keep hitting the following error messages:

srun: error: compute-42-013: task 32: Bus error

It seems the bus error is inside the MPI subroutine. Since I do not have the source code  of intel MPI, I have no idea what went wrong. 

The intel mpi version I'm using is intel_parallel_studio/2018u4/compilers_and_libraries_2018.5.274. 

Any idea how to fix it? 

Thanks.
