Hi, today we had an issue in production, and I have no clue what caused it. It seems like an issue with Next.js itself. I restarted the instance, and everything started running fine again....

There were messages like these all over the logs as users were trying to access the page. I have no idea what is running on port 127.0.0.1:54295; I assume it’s either calling some low-level Rust library or another Node.js process.

Any idea what may have caused this or how to prevent this. We host on digitalocean's apps.
