Subject: [PATCH 59/59] clock: Downgrade log message about failed uds forward.
|
|
|
|
If multiple management clients are used in the network and ptp4l
|
|
responded at least once over UDS, it will try to forward all management
|
|
responses received from network to the last UDS client. ptp4l doesn't
|
|
track the messages and doesn't know if they are responses to the UDS
|
|
client or other clients in the network. If the UDS client is no longer
|
|
running (receiving messages on its address), ptp4l logs "uds port:
|
|
management forward failed" error message. With frequent management
|
|
requests in the network this can lead to flooding of the system log.
|
|
|
|
Downgrade the error message to debug to disable it in the default log
|
|
level.
