Troubleshooting Rails / Puma locking up when running locally

Question

I've been having an issue where my local Rails / Puma server will lock up after running for a while. I suspect this may have to with the log data, but am honestly not even sure where to begin troubleshooting this.

What happens is that the server will lock up and is unresponsive, no log messages in console etc. The fix being to restart the local server. The odd thing is that when I run the command to stop the server (control + c) a bunch of normal log messages will be printed to the console before it shuts down. Additionally, I've noticed that if I periodically manually clear the console log (command + k) this doesn't happen. This leads me to believe that it may have something todo with a log file size limit.

I have not noticed this issue in any of the staging or production environments, only localhost.

Server is started with a Procfile using foreman with foreman start -f Procfile.dev

I'm wondering if this may be a STDOUT issue and not specifically related to Rails / Puma, but any advice in trying to track this down would be appreciated!

Current Local Setup (although this has been a consistent issue with pervious versions as well)

• macOS 13.6.1
• using bash (not zsh)
• Rails 7.0.8
• Ruby 2.7.8
• Puma 4.3.12
• Sidekiq 6.5.12
• foreman 0.87.2
