[Samba] FSMO DC giving curious log output

[Matthew Delfino]

Hello!

I’m seeing the following log entries in /var/log/syslog on my FSMO (Ubuntu 14.04.3 LTS / Samba 4.3.4):

Feb 19 09:56:48 dc00 samba[4552]: [2016/02/19 09:56:48.527183,  0] ../source4/dns_server/dns_update.c:426(handle_one_update)
Feb 19 09:56:48 dc00 samba[4552]:   Can't handle updates of type 255 yet

Feb 19 11:30:04 dc00 samba[4552]:   Can't handle updates of type 255 yet

I looked up type 255 in the context of DNS and found some information about it being a request for all DNS records. Has anyone seen this before? Could this be a normal message? Or is there something on my network requesting all DNS records from my FSMO DC?

DNS is Samba Internal, not BIND-DLZ.

Thank you in advance!
Matthew
