Bun crashed upon spamming HTTP requests which downloaded files

[Dawsson]

How can we reproduce the crash?

Unsure of what caused it. I was spamming POST requests to the server which downloaded a file and saved its hashed along with some other body data to a mongo database.

This was a Typescript, Hono, and Bun project ran using bun run --watch src/index.ts

Relevant log output

No response
