Flooded logs: `sem_get(): Failed for key 0x7ea: Permission denied at /var/www/html/nextcloud/lib/private/Preview/Generator.php#272`

I'm getting the below error even after removing preview generator

sem_get(): Failed for key 0x7ea: Permission denied at /var/www/html/nextcloud/lib/private/Preview/Generator.php#272

This isn't coming from the previewgenerator app (though it may be getting triggered by it I guess).

This is a Nextcloud Server matter, but I have no idea offhand why you'd be getting permission denied from sem_get.

Are you still seeing this? If so, please share the output of occ config:list system since it is related to the preview concurrency mode/ configuration.

I'll also go ahead and move this over to the appropriate repository.
