      Description

      This might be related to JENA-1908, but since the stack trace is different, I opened a second ticket.

      Tried to import the latest Wikidata dump into Apache Jena, using the following setup:

      • Ubuntu 20.04 on Windows 10 Subsystem for Linux
      • Apache Jena 3.15.0
      • Intel i7 4770K, 32GB RAM
      • openjdk 11.0.7 2020-04-14
        OpenJDK Runtime Environment (build 11.0.7+10-post-Ubuntu-3ubuntu1)
        OpenJDK 64-Bit Server VM (build 11.0.7+10-post-Ubuntu-3ubuntu1, mixed mode, sharing)

      These are the commands I have run:

      wget -c http://mirror.easyname.ch/apache/jena/binaries/apache-jena-3.15.0.tar.gz
      tar -xvzf apache-jena-3.15.0.tar.gz
      mkdir data
      apache-jena-3.15.0/bin/tdbloader2 --phase data --loc data/ ../latest-all.ttl > tdb1.log 2> tdb2.log &
      apache-jena-3.15.0/bin/tdbloader2 --phase index --loc data/  > tdb1.log 2> tdb2.log &
      
      

      The data phase ran fine, but the index phase crashed after about 10 hours. The stack trace is attached to this ticket (tdb2.log).

      Here's the standard output:

       08:47:57 INFO -- TDB Bulk Loader Start
       08:47:57 INFO Index Building Phase
