Same thing here. The updates seem to work fine but it always comes up with that same error since a couple of weeks ago. I’ve got 768M of PHP Memory and nothing showing up in the logs about it so not sure what’s causing it.
SOLVED…some research and…
i use ArchLinux and php-fpm. And for some reason max_execution_time in php.ini it seems nor work.
So, in /etc/httpd/conf/httpd.conf
add ProxyTimeout 360
