samba - Jul 2018 - samba_dlz b9_format: unhandled record type 0

Dual Samba 4.7.6 AD DC on Ubuntu 18.04 Servers + Windows 2008R2 DC.

Looking at Samba logs I've noticed a lot of these lines on first DC:
---
Jul 31 11:08:25 srvaddc named[32168]: samba_dlz b9_format: unhandled record type
0
Jul 31 11:08:25 srvaddc named[32168]: message repeated 92 times: [ samba_dlz
b9_format: unhandled record type 0]
...
Jul 31 11:19:12 srvaddc named[32168]: samba_dlz b9_format: unhandled record type
0
Jul 31 11:19:12 srvaddc named[32168]: message repeated 100 times: [ samba_dlz
b9_format: unhandled record type 0]
---

Thanks to rsyslog compacting identical and repeated log lines by default on
Ubuntu (the "repeated x times" part), this issue didn't leap out
immediately.
I'm actually a bit worried since it repeats each 10/15 minutes with about
100 (compacted) lines each, so I'm investigating on it but... no results.

The only relevant result I've found is this message from L.P.H. van Belle in
2014:

@Louis: did you fix the issue on your side?
@all: what shall I do?

Cheers

Hai, 


Hm, yes, i recall that but i dont remember how i fixed it. 
I've checked mail mails and review the old thread. 
Sorry, i dont have more on this for you. 

Do you know that exact moment when it started? Yes? 
Then search in you DNS zones for record with around that time, if possible
remove it or change/update it.
Make sure you have good backups! 

Greetz, 

Louis

I suppose it started from day 0 (my AD was migrated from Windows DC) but 
haven't noticed because of rsyslog compact and a lot of other stuffs to fix.

Since I'm sure that all of my DC are synchronized, is there a way to 
forcibly delete tombstoned AD items?
