Great to hear that this worked out for you in the end.

Well, as it turns out all my fault as another backup process I have kicked in
and interfered with my reprocessing. After I synchronized these two competing
resources everything runs as smooth as usual again.
Sorry for bothering but we are close to end of our release cycle ;)

P.S.
Neo rocks!
Thanks, I know :)

Betreff: [Neo] NPE during XA transaction
Hi,
I am trying to reprocess requests available from a queue into my neo store.
I intentionally avoid using the bulk load feature. The idea behind the
feature is to have the ability synchronizing neo with the database in case
neo missed transactions and also to be able to reconstruct the store from
scratch if needed. Everything works just fine when processing the queue in
production, that is, where requests come in infrequently, all distributed
during the day. It unfortunately fails when trying to reprocess them in fast
order. It consistently happens after approx 2000 processing requests.
Any idea what could have caused the NPE as pasted below? Looks like the
'LogBuffer writeBuffer' got assigned to NULL at one point, probably during
either releaseCurrentLogFile() or close(). Anything related to log rotation,
maybe? This happens on Linux with Neo4j 1.0-b10.
Any workarounds or explanations appreciated,
-Andreas
