Loading dbpedia.nq: exception in thread main gc overhead limit exceeded

Hi,

I am trying to load dbpedia in n-quads form (from BTC-2012 dataset). I am
using apache-jena-2.10.0. And for loading I used the following command (in
ubuntu 12.04 server, with :
$ cd apache-jena-2.10.0

./bin/tdbloader

--loc=/home/
jenaDbpedia -v /home/jyotil/dbpedia.nq

However, after loading a significant number of quads I am getting the
following error:
exception in thread main gc overhead limit exceeded?
