Fiber includes a built-in panic recovery middleware that catches panics in route handlers and middlewares, preventing the server from crashing and allowing it to recover. Alongside this, a stack trace handler has been implemented to store system panics in the context locals (stack). Both the S3 API server and the Admin server use a global error handler to catch unexpected exceptions and recovered panics. The middleware’s logic is to log the panic or internal error and return an S3-style internal server error response. Additionally, dedicated **Panic** and **InternalError** loggers have been added to the `s3api` debug logger to record system panics and internal errors in the console.
