Hallo everybody.

I get an exception that seems to occur randomly in a batch-dataimport.
The import handles a few hundred datasets correctly before the exception occurs.

Does anybody know this problem?

Odd. Check that you have the latest version/patch it may have been something fixed.

Otherwise try to create a test to reproduce the issue and log a bug.

I am also seeing this same problem intermittently. I think this may be a concurrency issue. I also see this error in the same place:

Seems to be a different issue. Please log a bug for it, and include as much detail as possible. If you can create an isolated test, that would be best.

What was the query you executed, and what are the other threads doing to get this error?
What type of batch fetching are you using, IN? Are you also using join fetching in the same query?
What version are you using, did you try 2.5? (can you include the stack trace from 2.5)

I'm running 2.3.2, I haven't been able to reproduce this locally yet, only in production under high load.

I'll see what else I can find and log a bug.
