Comment 6 for bug 1619508

Hi Cyril,

Thanks for looking into this. I think we have two possibilities to reasonably address this bug:
1) we prevent the process to start if db.simple and workers <1 is configured
2) we override the workers setting to 1 if db.simple is configured and log warning about it

In both cases good documentation is needed explaining why and how this is working on decided manner. We would also want to explain why one should not run multiple glance nodes in such cases.
