Hi there, I am running a NWChem job with the following input:
START compound
MEMORY stack 900 heap 100 global 2000 mb
TITLE "Compound : 3-21G* geometry optimization"
GEOMETRY NOCENTER NOAUTOZ NOAUTOSYM
 LOAD format xyz "slab.opt.xyz"
END
BASIS SPHERICAL

 ITERATIONS 1000

TASK DFT raman

where my geometry has 100 atoms, the largest is sulfur. I was running this job on a 8 core machine with 24GB ram.
Now I recieved this error:

Can someone explain me what happened? Thanks.
