after setting apc.enable_cli=1 in php-ini for cli and apache didn’t work (alone?)
i did find anything i found here,. including getting memcache out of conf.php
in addition i deactivated any additional apps, reinstalled my php-ast because i had some error messages belonging to that. don’t know what exactly it was, but after a reboot nc and cron.php are runing again without freezing the whole system and crashing mysql.
whatever it was what made this upgrade a pain in the ass, it would be great if nc’s upgrade process would be safer, it wouldn’t use any software which doesn’t come with actual repos like debian / raspbian / ubuntu and if it would be able to run on small/older computers in the future.
regards.
