- checked the logs /var/log/website/php_errors.log, nothing was found
- checked why it was returning an error and it's because of the backend somehow and varnish hit
sub vcl_error as a result
- it used to work yesterday and with no code change and no server change, it stopped working
- no exception logs from php
- no log from httpd that explains the shutdown, latest logs come from 3 days ago when the server was fine

Got this before I fixed it:
Error 500 Internal Server Error
Internal Server Error

- a reboot solved the issue, but how do I check what's causing apache to crash. Is there a way to log what's happening to the server? I am thinking it's a cronjob or some kind of script that takes a lot of memories and then crash the server? What might be the possible reasons why it crashed?
