Thanks for reporting this.

The Profile feature in the Console UI relies on a WebSocket-based profiling flow that was removed from the official minio/console in November 2024 (PR minio#3467).

The georgmangold/console fork we use restored it via a revert, but the underlying code hasn't been actively maintained since then. The broken pipe error you're seeing is caused by the Console's WebSocket client disconnecting before the MinIO server finishes writing the profiling data — a compatibility issue between the restored Console UI code and the current server, not a simple server-side bug.

Given the complexity and the fact that this feature was already deprecated upstream, I've decided not to fix the Console UI profiling path.

Workaround: Use the CLI instead, which talks directly to the server API and works reliably
