WRF fails with 3 domains but runs with only the outer domain

[nhuneeus]

Hello all
I'm trying to run WRF with an outer domain covering all of South America and two inner domains centered in Santiago (Chile). I then want to use the other domain to run smaller domains on other cities in South America. When running the three domains at once the model fails but it works when I run only the outer domain. I've tried several parametrization of previous successful simulations, all of them covering only a part of South America though. The last lines of the rsl.error.0000 of the simulation that fails are:

Timing for processing wrfinput file (stream 0) for domain 2: 0.14547 elapsed seconds

INPUT LandUse = "MODIFIED_IGBP_MODIS_NOAH"
LANDUSE TYPE = "MODIFIED_IGBP_MODIS_NOAH" FOUND 41 CATEGORIES 2 SEASONS WATER CATEGORY = 17 SNOW CATEGORY = 15

LANDUSE TYPE = MODIFIED_IGBP_MODIS_NOAH FOUND 20 CATEGORIES
INPUT SOIL TEXTURE CLASSIFICATION = STAS
SOIL TEXTURE CLASSIFICATION = STAS FOUND 19 CATEGORIES
forrtl: error (78): process killed (SIGTERM)

I have no idea what is causing this error. ¿Any ideas?
I'm attaching the namelist as well as the rsl.error.0000 and rol.out.0000

This is a complicated cases with triply-nested domain and spectral nudging. Without helpful error information, it is hard to determine why it failed.
Would you please turn off nudging first, then run the case and see whether it works? This will be helpful for narrowing down the problem.
Please start from 2-domain run, and then move on to 3-domain.
