Reading the console: "mDNS_Register_internal: ERROR!!"

[bbox]

Dear community and all concerned,

I have been trying to create users and groups (very fresh FreeNAS experience), and by the glimpse of an eye at the console, I've noticed that every time I press 'OK' for adding an user it comes up with following text:

Don't really know how to address an issue. Is it a bug? Should I report? Etc.

You can ignore the mDNS Responder messages. There is already a feature request to divert them:

Thank You, @dlavigne. Glad I've asked, good to know.
