Steps:

1. Use Elasticsearch as search engine on one repo (another repo might be necessary to finalise an item big enough).
2. Create Content Type with multiple* fields (* - very many, like PF project ref. IBX-2618).
3. Create Content Item based on this CT.
4. Add 20 translations.
5. Try to reindex using the repo with Elasticsearch.

Actual result: It's not possible to reindex. Neither locally or on Ibexa Cloud. Either docker container or nginx server crushes.
Expected result: It's possible to reindex using default number of iterations.

Remarks: Exceptions are attached.
