How to debug "received fatal signal"

Hi Prologgers,

I am running a Prolog program on a remote server to download all
Linked Open Data that is described in the CKAN repository datahub.io.
These are overall very big datasets and running the complete script
takes quite a while. For some reason that I would like to figure out,
the Prolog program stops with the below included output.

My question is: what would be the/a best practice to debug this in a
smart/focused way (i.e., except for populating most of my code with
debug statements)? Am I able to catch this error in C and then get a
little more info on what is in the Prolog stack at the moment the
exception is thrown?
