Could you please check the database file for errors using the ObjectDB Doctor?

Is this error consistent? i.e. do you get the same exception every time you run this specific query?

Thanks for taking care.

Yes.

I suspect a JVM memory shortage problem as I'm running in an embedded system (ODROID-C1) with limited ressources.

In the meantime I removed other JVMs running in parallel and made some optimizations and the problem did NOT re-occur.

So you do not need to follow this issue any more. I will report when I have verified it in more detail. I'll then try "ObjectDB Doctor" first.

You may close this issue for now.

Thanks

Leon
