Hi there,
i do a big import in my rdf-store using rdf4j 4.1.3
After a while i got the following error. When I try to submit a query after the process has stopped, a StackOverflow occurs again.
[OFF TOPIC: Do we have to discuss this on https://stackoverflow.com ;-)]

There are 4488 Publications of type CreativeWork in the store, see: https://linkedopenactors.gitlab.io/loa-specification/#information-exchange-data-model

Would you be able to share the data or in some other way help us reproduce the issue?

I was now able to dump the database from my server.
I put it in a local repository in a simple java application and query it with almost the same query.
But i'm not able to reproduce it.

^ the difference for now is, that i ignore the versions and the contexts, because the context are lost while dumping the database on the server.

is it possible to make an export with all contexts ? RepositoryConnection.export* is nice, but not really for a complete repo with contexts.

Export to TRIG format?

naturzukunft Nov 1, 2022

it would be replroducable with that scenario:

mkdir rdf4j
cd rdf4j
git clone https://gitlab.com/linkedopenactors/rdf-pub.git
git clone https://gitlab.com/linkedopenactors/loa-kvm-adapter.git
mvn -f rdf-pub/rdf-pub-core/ spring-boot:run -Dspring.profiles.active=local

You have to adjust credentials in rdf4j/loa-kvm-adapter/src/main/resources/application.yml
kvmAdminUserName: xxxxxxxxxxxxxxxx
kvmAdminPassword: xxxxxxxxxxxxxxxx
i would like to give you that in a more secure way!

"open new shell in same directory"
mvn -f loa-kvm-adapter/ spring-boot:run -Dspring.profiles.active=local
"open browser with 'http://localhost:8082/initialLoad?limit=2'"
"If that works, you can call 'http://localhost:8082/initialLoad?limit=ALL'"
