Error message

{errors joined with "; "}

What it means

A multi-step cleanup/teardown routine collects an error for each failed step (e.g. "remove turn operation binding: {err}") and, if any failed, bails with all messages joined by "; ". It signals partial cleanup failure: some resources (bindings, files) were not removed during thread/turn teardown.

Solutions

1. Parse the joined message to identify which steps failed, then fix each underlying cause (permissions, disk space, missing files).
2. Re-run cleanup/idempotent teardown — removal steps are typically safe to retry.
3. Check for concurrent processes holding the store and serialize teardown.

match runtime.teardown_thread(&id) {
    Err(e) => {
        for step in e.to_string().split("; ") { log_failed_step(step); }
        retry_idempotent_cleanup(&id)?;
    }
    Ok(()) => {}
}

When it happens

Trigger: Teardown where one or more removal operations (e.g. removing the turn operation binding) return Err — the errors vector is non-empty, so the aggregated bail fires instead of Ok(()).

Common situations: Read-only or full filesystem during cleanup; a binding file already removed by another process; permission errors on store subdirectories; transient store lock contention during concurrent teardown.

Understand the failure class

Background: "failed to write file", "Could not save figure", "Error saving remote file" — file write failed: causes and fixes across languages and libraries — this error's family across 38 libraries.
