62.5 Nextcloud Snap Configuration

Increase PHP Memory Limit

In my log file I had been seeing the entries:

Request used more than 300 MB of RAM: 495.9 MB

Allowed memory size of 536870912 bytes exhausted (tried to allocate
327680 bytes) at
/var/snap/nextcloud/48223/nextcloud/extra-apps/recognize/lib/Clustering/MrdBallTree.php#456

Checking the PHP memory limit:

$ sudo snap get nextcloud php.memory-limit
512M

The memory can be increased with:

sudo snap set nextcloud php.memory-limit=1024M
sudo snap restart nextcloud

The alternative is to edit the config.php file:

'php_memory_limit' => '1024M',

The error might be generated from the recognize app during clustering of facial images. We could run the clustering manually with a smaller batch size:

sudo nextcloud.occ recognize:cluster-faces --batch-size=1000

This did not result in the memory problem from my testing.

The automatic clustering can be disabled with a setting in config.php:

'cron' => [
    'recognize_clustering' => false,
],

The manual command could then be run as required, or by using cron.
