[Samba] Upgrade from 4.9.8 to 4.10.3 on Centos using Sernet Packages

Hello you all,
we have a 4 DC environment running on Centos7 with the Sernet-Packages.
Version on all DCs is 4.9.8 (smb.conf below). We upgraded one of the DCs
to 4.10.3. After a few minutes we see this in the logs:

The process is restarted and no apparent error is seen. As we had a
snapshot from before the upgrade we just reverted back to this and don't
see the panic anymore. Anyone has an idea how to debug this?

Why do you have a parameter with another parameter as its value ?

both 'logging' and 'syslog only' are both parameters, did you
mean
'logging = syslog' ?

Well virtually no is not no? I wanted to make sure.

To disable smbv1.

So I wouldn't have to change the firewall as it was setup with samba 4.4.
