I have seen this message after smbd has crashed on the server side
or smbd did not reply to a request by the CIFS client for a while and the
client then forcefully disconnected.

Maybe you can check for smbd crashes in the logs and if it is somehow
reproducible then gather smbd debug logs showing the last few minutes
before
the message had shown up.
