Andy, I am currently running with the TDB being written to my harddrive (of my Linux RHEL 64bit machine). This failure can sometimes take up to 3-4 hours before it fails. I have tried using a RAM dick but it fills up before the failure occurs as I can only give it 10Gb of space and due the test the TDB does get very large due to all the creates & deletes. I am running on RHEL 6.4 with the following JVM: java version "1.6.0" Java(TM) SE Runtime Environment (build pxa6460sr15-20131017_01(SR15)) IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Linux amd64-64 jvmxa6460sr15-20131016_170922 (JIT enabled, AOT enabled) J9VM - 20131016_170922 JIT - r9_20130920_46510ifx2 GC - GA24_Java6_SR15_20131016_1337_B170922) JCL - 20131015_01

As it may be a timing issue, do you have an SSD?
