samba - Dec 2024 - Samba Crashes on AD DC if "unix extensions" is Enabled

Is this another of those, "I told you not to have shares on your DC!" 
situations? (Moving away from them. Promise.)

I would not be surprised, the fileserver code is in /source3 whereas the 
DC code (and its file-sharing subset) are in /source4...
I would think (i.e. not verified) that unix extensions for smb3 (as they 
belong to the file server) have landed in /source3. As you can see in 
the log, your code failed in /source4.

I would like to see the lines above that, it is possible that you are
starting the wrong binary.

You still appear to be using init.d scripts and the 'samba' init.d
script used to start the smbd & nmbd binaries, on a DC you should start
the 'samba' binary (not to be confused with the 'samba' init.d
script)
and this starts smbd and winbindd.
