3422330 - Missing logs after deployment

Image/data in this KBA is from SAP internal systems, sample data, or demo systems. Any resemblance to real data is purely coincidental.

Huge number of the logs is missing after the deployment. In the HAC, logging list is empty for all nodes.

Furthermore, in the logs below errors can be observed:
