For directly connected nodes (point-to-point or ethernet), I usually get
a log notification whenever a node comes or goes. That is pretty much
standard DECnet logging.
And it's event 4.15 for adjacency up, and 4.18 for adjacency down.

I had been wondering why nobody else appears to be
seeing these
particular messages on Tops-10/Tops-20. It occurred to me that the
reason for this is that the default PANDA configuration doesn't enable
their display. If you haven't already done so, then may I suggest
adding the following lines to SYSTEM:SYSTEM.CMD?
;; Change default PANDA logging. We want to know what's going on
Enable Output-Display BUGINF-Messages
Enable Output-Display BUGCHK-Messages
Enable Output-Display System-Messages
Enable Output-Display All-Messages /Information-Messages
Enable Output-Display All-Messages /Job-Messages
Enable Output-Display All-Messages /OPR-Action-Messages
Enable Output-Display DECNET-EVENT-MESSAGES
Enable Output-Display DECNET-LINK-MESSAGES
Among other things, the commands condition some Galaxy component (I
think NMLT20 on Tops-20) to do the equivalent of a NODE% JSYS to perform
a .NDSIC which enables the fork to receive node topology change
interrupts. However, as these are Galaxy OPR commands, they should be
compatible for Tops-10 as well.
The question is whether the messages are indicative of any real issue or
whether it's a perfectly fine informative notification of, "Hey, I can't
talk to 28NH::". Normally, I only see such alerts when I make an
/outgoing/ connection to a node that is not online. I don't see
anything else, even in the local area. At one point in Phase III, I
would see when nodes coming on and offline, which was kind of cool.
If you do the above and perchance see any messages like the below, then
I suggest that you please pass them on to Paul so he can see if there
are any correlations with what he's doing.

I have Galaxy set to log DECnet events. For what it's worth, every so
often I see the following on my Tops-20 console:
23:19:48 -- DECnet link message --
Communication failure to the following nodes:
28NH
Since January 16^th of 2021 (last year), it's happened as 44 times on
TOMMYT:: Sometimes it's frequent over a few days, sometimes I can go
months without seeing them. For example, nothing since July. I'm not
sure this has anything to do with the RSTS failure mode. Absent
further information, I'm more inclined to believe that Tops-20 isn't
handling a close properly or something has decided to time out.
Aside from the below, I don't have additional data (all times Eastern)

It's possible that SPEAR could get some more information on this; I
haven't looked.
