The preexec / postexec hooks mentioned at
https://unix.stackexchange.com/a/478881/275843 work well for this. I
see Mac clients disconnecting when they have problems, but haven't yet
correlated that occurrence to anything suspicous in the log.smbd file yet.

I haven't noticed this. What do you look for to find this?

These questions are hard to answer. I have the suspicion that there is
more than one problem going on AND my end users have just lived with it
I need to do more testing before I have enough to go on before using
someone like Rowland's time. :)
For example, one failure mode is that sometimes macOS (10.13 ,10.15, ?)
will block access to paths hosted by Samba. It is most easily
reproducible if a DFS link is involved. So far I know this happens with
Samba 4.9.17, 4.10.11, and 4.11.4 .
Try searching for "finder" and "sandbox" in Console of a Macintosh which
is having problems. Press "return" after each term so you're not
searchign for "finder sandbox" but "finder" AND "sandbox".
Eventually I'll submit a bug report on that, but need to write it up.
That is not the only problem however.
