Hi,
I am running an electronic structure minimization job with spin orbit coupling. The job runs fine for a couple of iterations and then crashes. It gives the following error message after killing the job.

forrtl: error (78): process killed (SIGTERM)
Image PC Routine Line Source
libmlx4-rdmav2.so 00002AAAB4A2E318 Unknown Unknown Unknown
mpiexec: clean termination accomplished


Everything is working fine for smaller jobs (8 atoms in the cell). The above job has 64 atoms. I am running the job on 121 procs. I am not sure about the source of this error. Kindly let me know if any input is given wrong. I have attached my INCAR and POSCAR file.
