I'm getting a Server Error 500, and have no idea why

Installation

I don’t know if this is related to my previous post, but I’m currently getting a Server Error 500 on my forum:

https://talk.birmingham.io/

I had reports that it was down over the weekend for an amount of time also, but appears to have sorted itself out last time.

Any ideas?

Quick update - I rebooted the server, and the site is back up again now.

What can I do to check what went wrong?

Some logs are available under http://discourse.yoursite.com/logs if you’re an admin.

More logs are available by SSHing into your Docker installation and looking in /var/www/discourse/log

I’m looking at the logs in /logs, and I’m getting entries like this:

Job exception: Cannot allocate memory - df -Pk /var/www/discourse/public/uploads/default | awk ‘NR==2 {print $4 * 1024;}’

I’m running on DO’s $20 a month box.

I can’t access the server logs until I get home.

Looks like you’re experiencing the recent memory leak bug, too:
