-----------------------------------
The exception as shown in the description is the most common and has been
observed on both 0.9.1 and 0.9.4. However, the following exception very rarely
occurs instead (also seen in both 0.9.1. and 0.9.4):

> Key: JENA-308
> URL: https://issues.apache.org/jira/browse/JENA-308
> Project: Apache Jena
> Issue Type: Bug
> Components: TDB
> Affects Versions: TDB 0.9.1, TDB 0.9.4
> Environment: Windows 2008/7 (64 bit) both on IBM and SUN JVM 6.
> Direct mode
> Reporter: Simon Helsen
> Priority: Critical
>
> We are faced with a series of possible exceptions which may or may not occur
> after an active tdb store is killed. The most common exception has the form:
> Exception in thread "Thread-3"
> com.hp.hpl.jena.tdb.transaction.TDBTransactionException: Feaild to read block
> checksum.

> Other exceptions are possible (see comments below). I have been able to
> produce a standalone java program/test case which simulates a process kill
> and is able to produce the exception after a non-deterministic time. It runs
> an iteration until it hits one of the possible problems. Sometimes, an
> exception hits after just 2 iterations, other times, it can take 40 runs or
> more before hitting a problem. Because I don't know what the cause is here, I
> have not been able to make the test case more specific
