Diameter bridge query timed out

Logged when a named bridge query cannot complete peer selection, sending, and answer reception within its backend action timeout. The deadline also covers the Session-Termination-Request sent after an accounting STOP; the diameter_command_code field shows which request expired. The backend timeout counter is incremented.

Check connectivity and response times for the logged server and peer group, and compare the backend's request and timeout counters. Adjust the backend action timeout when the peer's expected response time requires it.
