Describe the Bug

Error in log file (I always get them two at the time). At night I receive them (probably the cron job) and also when uploading (multiple) images.

[PHP] Fout: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 655360 bytes) at /var/www/cloud.DOMAIN.TLD/html/apps/recognize/lib/Clustering/MrdBallTree.php#450

I have these errors for a long time.

My PHP info:

Version: 8.2.12
Memory limit: 1 GB
Max time: 3600
Max. upload size: 1 GB
Frequentie OPcache validation: 2

Extra info, probably not relates:

Also after manually downloading the models, this status keeps returning

Expected Behavior

I don't expect an error. I have no clue if this means the image is not analysed

To Reproduce

1. Uploading images (I think it's always with multiple images)
2. cron job at night

Debug log

No response

Start at apps/recognize/lib/Clustering/MrdBallTree.php around line 450 and reproduce the failure during multi-image uploads and the nighttime cron job. Check how the face-recognition clustering path uses memory under the reported 1 GB PHP limit. Done means the reported processing completes without the memory exhaustion error and its behavior is verified for both triggers.
