Hi Beatrix,

We talk here about your test with 5.0 beta?
Or this happens in 4.9 for you?  Or 4.9 was fine in this place?

PLEASE -- discuss 5.0 on beta list to not mix things...

To do EXPORT, you just do many READs record by record,
Then your code produce some file on disk ..

Then you stop this operation -- nothing for db
Then you RELOAD something -- and I think here crash happens ...

Yes you should isolate it better ...
