-----------------------------------
in 0.9.1 (not yet seen in 0.9.4), we also sometimes see:

This was the original exception which triggered my investigation. It was
observed by one of our clients after a windows 2008 server machine was rebooted
killing the Java process. It is unclear if this issues has disappeared in 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
