@Jonathan Lamothe The stable release introduced several costly database updates since the search index has been reworked. Please make sure your database schema is up to date with bin/console dbstructure update. It should have been automatically updated with a run of the background worker but it's possible you have a different setup.

@Hypolite Petovan Forgot there was a web interface for the logs. Here it is:
Error: Call to undefined function Friendica\Util\idn_to_ascii() in /var/www/friendica/personal/src/Util/Network.php:543
Stack trace:

Looks decidedly not like a memory or database issue.
