Recently I experienced a staging server running out of memory and after researching we found a log file that was 17g! Removing the file cleared it up but it would be nice to not worry about it again.
Servers for Hackers has a tutorial on this exact issue:
Laravel Forge (and Envoyer) keep your Laravel application’s storage directory persistent through deployments. One side effect of this is that your storage/logs/laravel.log file is always growing.
Linux systems come with Logrotate, which can help us manage your growing log files. It’s really simple – we can basically set it and forget it.
On your Forge installs, it’s a good idea to set this up and you can read the full article on Logrotate for Forge and be setup in a few minutes.
