I saw the messages going by in the screen while the machine hibernates.
The timestamp corresponds to the thawing, because then is when it has a chance
to write them:

It may be related to these entries in the sender machine log:

I think that it is not that the receiver has the port closed, but that the sender machine is halting its own network service causing spurious log entries on the firewall (when packets can not be sent by the kernel netconsole), with incorrect content.
