timed out acquiring delegated coordination lock for {}: {err

Error message

timed out acquiring delegated coordination lock for {}: {error}

What it means

Timeout branch of the delegated coordination lock: ready_rx.recv_timeout(5s) elapsed without the lock thread reporting success or failure, so acquisition status is unknown. The {error} is the recv timeout error; the lock thread may still be blocked on the file lock for the given state_root.

Solutions

1. Check for a stuck holder of the coordination lock and release or terminate it
2. Retry the acquisition once the contention clears — the timeout is 5 seconds
3. If the lock thread hangs permanently, remove the stale lock file after confirming no live holder
