Andy, My setup is messy (and at home while I am at work). I was working at creating an extract and loading it into a TDB backed graph, so I just grabbed the recent releases. I am running on Ubuntu. I was not closing the graph before I exited and so caused the corruption. Adding the close and not aborting the process in the middle solved the problem.
