JVM SIGSEGV while retrieving and storing properties from DBpedia

Good evening,
I'm trying to run a simple program whose aim is to save in a TDB index
some properties that I've downloaded from the DBpedia endpoint. After
some hours of operations I receive a SIGSEGV from the JVM on my
archlinux x64 workstation. Have you ever got something similar? Maybe
could it depends from the heap's maximum size of the JVM?
This is the log of the execution, I hope that could help:

Thank you in advance,
