Error message

tasks running the health check server should not panic or be cancelled

What it means

The JoinHandle for the spawned health check server task returned an error, meaning that task panicked or was cancelled instead of finishing. The `.expect` encodes the invariant that the health server runs until shutdown; a JoinError here points to an internal bug or external task abort.

Solutions

1. Inspect the panic backtrace and logs around the health server failure
2. Rule out external cancellation (runtime shutdown, test timeouts)
3. Report the issue with full logs if the cause is not identifiable
