Emission

Log level: DEBUG

Per-request tracing: No

Promotion: WARN

Logged when a backend action reaches its timeout while queueing a request or waiting for the backend result. Radiator stops the action without trying another server.

The timeout_phase field is queue when the backend worker queue did not accept the request. It is reply when Radiator was waiting for the worker to finish.

Check timeout_phase, server_name, backend counters, and backend latency. Correct queue pressure or slow backend processing before changing the backend action timeout.
