Hey @joshtrichards sorry to bother .

Thanks for the update so under the Nc29 backport till shows 10mb but under the original pull the 10mb was changed to 50 ?

[joshtrichards]

@AndyXheli Indeed. Finally got around to addressing the failed automated backport draft just now. #45843. Will be merged into v29 branch after tests pass.

Hi still seeing this on NC 29.0.4

OCA\\Recognize\\BackgroundJobs\\ClusterFacesJob

@AndyXheli That's a job in the Recognize app. The issue here was just to clean things up to avoid too many false positives. The logging is legitimate. Issues with individual jobs need to diagnosed in relation to the individual apps providing the jobs to assess whether such high memory usage is expected or not/etc.

Hi @joshtrichards thank you for the detailed explanation. Much appreciated

Thanks Josh for explanation, but I am so going to swap that $logger-> to debug in my instance first thing in the morning. Honestly, this is exactly material for debugging, for devs to get feedback and optimize or fix if possible. Average user will just have huge log file for nothing.

If it helps my culprit is Cron job used more than 300 MB of ram after executing job OCA\Maps\BackgroundJob\AddPhotoJob but even if it gets noticed I doubt it will be improved in next ~2 years.

@luxzg If you feel up to it, probably worth reporting at https://github.com/nextcloud/maps since we can't address that here in server.
