Hi All:
I have a tdb dataset with almost 1g. I am trying to modify with using
Sparql update, however I get this error:

I'm afraid it looks like the dataset is corrupt. This happened sometime
in the past, probably due to the JVM crash or exiting without a sync()
being called.
From the stacktrace, I don't see any sign you are using transactions.
One of things transactions gives you is resistance to crashes. Used
directly, the code assumes you will cleanly exit the JVM - no crashes,
no exit without calling sync().
