Hi there,
A possible cause is not shutting the database down cleanly sometime
earlier. Could that have happened?
(Transactions will help a lot here).
Andy
PS Which version is this?

Hi
I’m working with Jena TDB and my data storage is on a clustered data server.
I got this exception:

There is no concurrency issues because the environment we work in is not
federated (i.e. no multiple clients calling jena).
I saw a post of Andy which implies that the datastore might be
inconsistent which worries me allot.
Can you provide some info why would this happen even though I never
encountered this and here we don’t deal with multiple concurrent requests.
Could this happen let’s say if data server was unavailable for a brief
moment ?
Really appreciate your help.
Thanks,
