"matchname failed" messages repeating endlessly

[BlazeStar]

Using 9.3

I keep getting these messages in the console.

Apr 8 03:01:42 NAS smbd[23821]: STATUS=daemon 'smbd' finished starting up and ready to serve connectionsmatchname: host name/name mismatch: 10.99.99.150 != (NULL)

10.99.99.X is a network I created without a DHCP server just to connect my FreeNAS system to my virtualization nodes so I can mount NFS shares without going through all the network.
All systems on this network are static IP configured.
10.99.99.150 is a virtual CentOS machine I use to mount some folders and make them accessible via sFTP (I never want to expose FreeNAS to the interwebz so that's what I did it this way)

I use to see such messages in the console before updating to 9.3, but now, they're repeating these (above) every 30 seconds. LITERALLY.

So my message console is completely unusable as: all I see, all the time, is this crappy message repeating over and over.

To monitor my stuff I can't even use the console from the web GUI I have to grep my shit from the shell.

How can I stop this nonsense?

Unchecked 'hostname lookups' in cifs config.

Alright! Man that was easy.

Thanks!
