"Something went wrong, please try again" message

**Describe the bug**
When I had a few persons ( subjects) stored in Compreface, the facial recognition worked just fine.
Now there are approximately 8K persons added and the face recognition simply returns:
`[message] => Something went wrong, please try again
[code] => 0`

This goes for both the API and the admin interface

Other API's still work fine by the way. I can fetch the subjects and the images.

**To Reproduce**
Steps to reproduce the behavior:
1. create approx 8K subjects, having approx 166K photos.
2. try the face recognition API and then the message appears.

**Expected behavior**
So maybe this system is not designed for this much subjects and images, but I sure would like know where the limit is and which approach would be best in my usecase.
