DM,
I've noticed recently that my production instance of sbbs on RPi4 that is running current latest build seems to be ignoring semaphore files to trigger services restarting. Also, if I run /sbbs/exec/sbbs interactively, the recycle command is ignored regardless of the service type that is specific.
On my x64 test system, I did a clean install of the latest build and I could recycle the services interactively and all of the semaphores seemed to work except for telnet.
What are some places I could further investigate to understand what is happening?
The log output. Look for something like: "Disabling Terminal Server recycle support". This indicates that you're runing sbbs as root, with it changing to a different user-id, but you don't have the capabilities library installed. Use 'setcap' instead: http://wiki.synchro.net/howto:linux_non-root

Here's the beginning of my console log:

So you're right on the money about the indicators, however, I am using setcap and have compiled with the same options on both systems.
I tried to reissue the apt-get install command:

Note, selecting 'libcap-dev' instead of 'libcap2-dev'
libcap-dev is already the newest version (1:2.25-2).

Any ideas?

In addition to using setcap on all of my installs, I've also setup authbind too and it exhibits the same symptoms.

You shouldn't need to start the BBS as 'root' then. Instead, start it as the user you intend to run it as and you can remove the User/Group settings from the [unix] section of your sbbs.ini file.

Also, I never have called sbbs as root. I've rotated between authbind/setcap. It might help to put additional remarks in the sbbs.ini file for folks like me to not populate those fields unless calling sbbs from root.
How's this?

That is fantastic! Please tell me that was not there the entire time. If so, I will accept your scorn and RTFM shame.
I just added the blurb "If you are not starting sbbs as root, then you should not set these values"
